The polymerization of three typical aromatic solvent-doped fullerene materials with similar hexagonal closest packed (hcp) structures (mesitylene/C60, m-dichlorobenzene/C60 and m-xylene/C60 solvates) is studied under high pressure and high temperature (HPHT, 1.5 GPa, 573 K and 2 GPa, 700 K, respectively). Raman and photoluminescence spectroscopies reveal that the intercalated aromatic solvents play a crucial role in tailoring the extent of polymerization of C60 molecules. In the solvates, the solvents confine formation of covalent bonds between C60 molecules to the 001 direction and the (001) plane of the hcp lattices, leading to the formation of mixed polymeric phases of monomers, dimers, one-dimensional (1D) chainlike oligomers, and two-dimensional (2D) tetragonal phase polymers under suitable HPHT conditions. The type and number of substituent groups of the aromatic solvents are found to have significant influence, determining the amounts and types of polymeric phases formed. Our studies enrich the understanding of the formation mechanisms for controllably fabricating polymeric fullerenes and facilitate targeted design and synthesis of unique fullerene-based carbon materials.

Atomic force microscopic studies have been conducted for insight into the morphological aspects of monochelic porphyrin and fullerene complexes forming fibrils of continuous nature. Alternating dark and bright segments could be envisioned clearly, as individual porphyrin-fullerene repeating units. These fibrils also caused a remarkable red shift in the soret band absorption of porphyrin. Dynamic light scattering analysis was also conducted under different solvent conditions, which showed the swelling of fibrils when the solvent was changed from THF to water.

Compared to conventional configurations, inverted organic solar cells (IOSCs) demonstrate superior stability, holding greater potential for commercial application. However, their performance is constrained by inherent limitations of the commonly used zinc oxide (ZnO) electron transport layer (ETL). Herein, we introduce tin oxide (SnO2) as a replacement ETL, leveraging its higher electron mobility and enhanced environmental stability. To further address interfacial issues, the SnO2 surface is modified with a C60 self-assembled monolayer (C60-SAM), which can passivate surface defects, optimize the energy-level alignment, and improve interfacial contact. Systematic studies comparing ZnO, pristine SnO2, and SnO2/C60-SAM as ETLs validate this approach. In devices based on the PM6:L8-BO system, the SnO2/C60-SAM ETL delivers a champion power conversion efficiency (PCE) of 18.39%, outperforming those with pristine SnO2 (17.92%) and ZnO (16.91%). These devices also exhibit improved operational and shelf-life stability. Moreover, applying this strategy to a ternary PM6:BTP-eC9:L8-BO system elevates the PCE to 19.05%. This work not only confirms the superiority of SnO2 over ZnO as an ETL but also provides a facile and effective interface-modification strategy, paving the way for developing high-performance and stable organic photovoltaics.

GeTe, a promising p-type thermoelectric material, faces challenges in scalability and stability due to complex compositions. We introduce a simplified strategy by incorporating minimal C 60
( ≤ 0.4 wt % ) into GeTe, leveraging interface mismatch to optimize electrical and thermal properties. C 60 reduces lattice thermal conductivity by ∼ 33% and enhances the Seebeck coefficient, achieving a power factor of ∼ 42 . 8 μ Wcm −1 K −2 . The GeTe-0.2 wt % C 60 C60 sample attains a maximum ZT of 2.15 at 773 K and an average ZT of 1.30 (323–773 K), surpassing comparable systems. This work highlights interface engineering for advancing thermoelectric materials and improving commercial viability.

The high catalytic activity of Cu-based nanozymes mainly depends on the efficient Fenton-like reaction of Cu + / H 2 O 2 , but Cu + cannot exist stably. Trying to find a material that can stably support Cu + while promoting the electron cycle of Cu 2+ /Cu + still faces serious challenges. C 60 is expected to be an ideal candidate to solve this problem due to its unique structure and rich physicochemical properties. Here, we designed and synthesized a C 60 -doped Cu + -based nanozyme (termed as C 60 -Cu-Bpy) by loading high catalytic active site Cu + onto C 60 and coordinating with 2,2′-bipyridine (Bpy). The single crystal diffraction analysis and a series of auxiliary characterization technologies were used to demonstrate the successful preparation of C 60 -Cu-Bpy. Significantly, the C 60 -Cu-Bpy exhibited superior peroxidase-like activity during the catalytic oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB). Then, the catalytic mechanism of C 60 -Cu-Bpy as peroxidase was elucidated in detail, mainly benefiting from the dual function of C 60 . On the one hand, C 60 acted as a carrier to directly support Cu + , which has the ability to efficiently decompose H 2 O 2 to produce reactive oxygen species. The other was that C 60 acted as an electron buffer, contributing to promoting the Cu 2+ /Cu + cycle to facilitate the reaction. Furthermore, a colorimetric sensor for the quantitative analysis of bleomycin was established based on the principle of bleomycin specific inhibition of C 60 -Cu-Bpy peroxidase-like activity, with satisfactory results in practical samples. This study provides a new strategy for the direct synthesis of Cu + -based nanozymes with high catalytic performance.

Constructing 1D/3D heterojunctions at the top interface has emerged as a promising strategy to mitigate non-radiative recombination and improve the stability of perovskite solar cells (PSCs). However, rational molecular design principles of organic components remain elusive, and the morphological instability of fullerene-based electron transport layers has been largely overlooked. Here, we introduce a heterocyclic amidine-functionalized molecule, 1H-pyrazole-1-carboxamidine hydroiodide (PCAI), to construct a 1D/3D heterojunction at the perovskite/C 60 interface. The molecular design features multiple hydrogen-bonding sites, an extended π-conjugated plane, and compact cationic size, enabling selective formation of phase-pure 1D (PCA)PbI 4 perovskitoid, while residual PCA + cations uniformly coat the perovskite surface. This surface reconstruction effectively suppresses non-radiative recombination and optimizes energy-level alignment, yielding a record-level power conversion efficiency of 26.33% among 1D/3D heterojunction-based PSCs. More importantly, PCAI acts as a “molecular glue” that anchors C 60 molecules on the perovskite surface, suppressing C 60 self-aggregation and preserving interfacial integrity under operational stress. This work establishes a clear structure–property–performance relationship for material design and identifies C 60 morphological evolution as a decisive yet previously underexplored stability factor.

A new type of temperature-responsive electrochemical sensor was constructed based on a glass carbon electrode modified by the composite containing temperature-responsive polymer polystyrene-poly N, N-diethyl acrylamide-polystyrene (PS-PDEA-PS) and fullerenes-carboxylate multi-walled carbon nanotubes (C 60 -MWCNTs). The sensor was used for the electrochemical detection of catechol (CC). When the temperature is higher than the critical temperature (LCST) of PS-PDEA-PS, the electrochemical behavior of CC can be detected, which it is in the “on” state. When the temperature is lower than LCST, the composite modified film is in the “off” state and the electrochemical behavior of CC was not detected. Under the best experimental conditions, the sensor has a good detection range for catechol from 4.0 to 135.0 μM, with a LOD of 1.45 μM. In addition, the proposed sensor has good stability and reproducibility, and was successfully applied to the determination of catechol in real tap water.

Carbon-based nanomaterials are extensively utilized as additives to enhance microbial activity in pollution remediation. A significant challenge to the widespread adoption of the full-scale anaerobic ammonia oxidation (anammox) process in wastewater treatment is the limited activity of anammox bacteria. Thus, this study investigates the effects of supplementation of fullerene (C60), a carbon-based hollow spherical molecule, on anammox granules, aiming to enhance the efficiency of wastewater treatment by stimulating anammox bacterial activity. The optimum dose of C60 was 25 mg of C60/L of the reactor working volume, which resulted in increasing anammox activity by 22% and the abundance of Candidatus Brocadia from 12 to 20%. The main mechanism for enhanced anammox activity was proposed to be associated with the accumulation of c-di-GMP signal molecules, which was driven by increased c-di-GMP synthesis protein (diguanylate cyclase) and decreased c-di-GMP degradation protein (specific phosphodiesterase) at 25 mg C60/L addition. The protein abundances responsible for the assembly, biogenesis, and stability of pilus were also increased, which might improve extracellular electron transport and accelerate the enzymatic reactions during the anammox process. However, higher C60 dosages (50–100 mg C60/L) inhibited anammox activity and abundance. The economic evaluation revealed a substantial increase in net present value (NPV) from $2,670 to $7,110 with the addition of 25 mg C60/L, emphasizing the economic viability of C60 supplementation for enhanced nitrogen removal in anammox-based wastewater treatment systems. Overall, this study proposes a novel and economically viable approach by supplementing C60 at 25 C60 mg/L (i.e., 3.5 mg C60/gVSS) to stimulate the activity of anammox bacteria, offering promising applications for real wastewater treatment plants.

To address the growing need for high-performing and stable energy storage devices, optimizing the durability and structure of supercapacitor electrodes is crucial. Traditional electrodes frequently face challenges in achieving an optimal balance between electrochemical capacity and structural stability. This study presents the synthesis of TiO 2 /CC@C array electrodes through ultrasonic disorder-induced deposition (UDID), specifically for high-performing supercapacitor applications. The impact of different ultrasonic power levels (50–200 W) on the electrodes’ structural and electrochemical properties was systematically examined. SEM analysis indicated that the sample prepared at 150 W showed an optimal, densely packed array of TiO 2 nanorods with improved surface uniformity, facilitating efficient ion transport. The 150 W TiO 2 /CC@C sample displayed a 46.73 m 2 /g specific surface area and a mean pore diameter of 9.35 nm, contributing to improved charge storage capacity. Raman spectroscopic analysis further confirmed the successful synthesis of the TiO 2 /CC@C composite, revealing distinct TiO 2 and carbon-related peaks. Electrochemical measurements showed that this electrode attained a specific capacitance of 687.3F/g at a scan rate equal to 5 mV/s. The system delivered an energy density equal to 158.4 Wh/kg at a power density of 20 W/kg when assembled as an asymmetric supercapacitor (ASC) with AC as the positive electrode. Furthermore, after 10,000 cycles, it maintained 86.3 % of its initial capacitance demonstrating outstanding cycling stability. These findings indicate that optimizing ultrasonic power to 150 W significantly improves both the structural and electrochemical performance of TiO 2 /CC@C, making it a promising candidate for advanced supercapacitor applications.

Till now, there is still a lack of the convenient and efficient approach to implement identification and quantitation of fullerenes in various domains. This work provides the first example for detecting fullerenes by an adequate fluorescent probe, in parallel with the new methodology for detecting fullerenes by the fluorescent chemosensing approach. Using a multi-emission lanthanide-disalicylaldehyde coordination hybrid H 2 Q j2 /Tb 0.91 Eu 0.09 , the rapid, selective and discriminative detection of analogous C 60 and C 70 can be easily achieved after the spectral and statistical analyses of fluorescent sensing signals on four emission bands (416, 543, 447 and 615 nm), excited by two irradiation lights (370 and 394 nm). Titration experiments further verify the very high linearity for both C 60 and C 70 and allow their detection at concentrations as low as 1.72 μM (C 60 ) and 0.09 μM (C 70 ). Moreover, this fluorescent probe also shows its reliable abilities to identify proportional C 60 /C 70 mixtures and monitor C 60 and C 70 contents in actual soil sample. It is believed that our proposed lanthanide-base fluorescent matrix not only verify the feasibility and potential of fluorescent chemosensing methodology for the fullerene detection but also provide a valuable tool for potential applications.

Photoelectric memristors, with the advantages of low-power consumption, high scalability and high parallelism, have provided a way for broadening the application of memristors. Photoelectric memristors based on heterojunction structures have gained high-performance in simulating biological synaptic plasticity and visual synaptic bionics. However, the effective separation and migration process of photo-generated carriers and the carrier dynamics mechanism is still the key factor and urgently need development. In this study, we proposed an optoelectronic memristor based on the MEH-PPV/C60 heterostructure to simulate neural synaptic functions. Compared with the monolayer structure, the heterojunction devices exhibited an improvement in both optical and electrical performance. Various synaptic behaviors were successfully emulated under light and electric stimulation signals. The photo-luminescence (PL), time-resolved PL (TRPL) and transient absorption (TA) spectra measurements were utilized to analyze and reveal the carrier transport mechanisms of MEH-PPV/C60 heterojunction. Due to the effective electron-hole separation by the built-in electric field at the heterojunction interface, the memristor based on MEH-PPV/C60 heterojunction exhibited superior electrical and optical performance. A 3 × 4 memristor array was constructed to simulate the human visual system to perceive and remember images and an artificial visual system with fear sensing capability was presented, which achieved four key features of human visual fear receptors (threshold, no-adaptation, sensitization and relaxation). This work provides strategies for the development of future memristor structures and the construction of human-like visual systems.

Kaempferol (KA), which is a biologically active natural polyphenol compound with considerable medicinal value, can be used to fight various diseases. Herein, a β-cyclodextrin/fullerene-graphene oxide/Nickel-metal–organic framework (β-CD/C 60 -GO/Ni-MOF) composite-based electrochemical sensor was developed to detect KA; the composite was characterized using scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and X-ray photoelectron (XPS) spectroscopy. The biocompatibility and host–guest recognition performance of β-cyclodextrin (β-CD); the porosity and the catalytic performance of the nickel-metal–organic framework (Ni-MOF); and the excellent electrical conductivity of fullerene-graphene oxide (C 60 -GO) work together to considerably improve the detection performance of the sensor for KA. The sensor has an extensive linear range (0.5–50 μM) and a low detection limit (58 nM) with an electrochemically active specific surface area of 0.0971 cm 2 ; furthermore, the redox mechanism of KA in the sensor is explained. For the detection of actual natural samples of broccoli containing KA, satisfactory recovery rates and accuracy were observed; the recovery rate was 96.4 %–101.1 %.
