We report the preparation of honeycomb structures (HCSs) by the breath figure method with high contents of fullerene C60 (>60 wt %) with a series of monosubstituted C60 derivatives (fulleromonodendrons) terminated with oligo-poly(ethylene oxide) (o-PEO) chains. It was found that a fulleromonodendron with two terminal o-PEO chains substituted at the 2,4-position of the benzene ring is the best candidate for the preparation of HCSs. The C60-based HCSs have hierarchically organized pores locating both on the film surface and inside the film. After blending with branched or linear polystyrene, the surface morphology and the internal structure of the film were further optimized. In addition, new functions such as photoluminescence have been introduced to the film. On the basis of the investigation of the aggregation behavior of the fulleromonodendron in CHCl3 as well as the exploration of the molecular organization and optical and electrochemical properties of the HCSs, the mechanism behind the film formation has been deduced. These hierarchically organized porous films with unprecedentedly high content of fullerene C60 may find applications in sensors, catalysis, and template synthesis of functional materials.

Three-dimensional Ag(I)-fullerene hybrid microcrystal is fabricated by AgNO 3 assisted liquid-liquid interfacial precipitation, containing the abundant sp 2 -π-electron system. With a mild chemical reduction, it produces the massive Ag nanocluster/fullerene junctions, on which fullerene doubles role as the excellent electron acceptor and photon scavenger, enabling the Plasmon-driven catalytic reaction. Ag nanocluster employed alone could not perform this photocatalytic reaction, neither of fullerene (C 60 ) crystal. It implicates that Ag-fullerene interface is a key to drive catalytic process. Relative to conventional TiO 2 nanostructures, fullerene expands light absorption to most solar wavelength and possesses a tightened bandgap which intrinsically expedites the charge transfer and charge separation from coinage metals. Demonstrated by photodegradation of organic molecules, this Ag(I)-fullerene (C 60 ) composite, consisted of a plethora of electron donor-acceptor dyads renders an additional member to photocatalyst family, potentially implemented for photo-electron conversion, water remedy and beyond.

The topological nanopores of covalent organic frameworks (COFs) are promising platforms for constructing photocatalytic nanoreactors for CO 2 conversion. However, simultaneously increasing electron density, promoting electron transfer, and enhancing CO 2 adsorption and activation within confined nanopore spaces remain critical challenges for boosting photocatalytic performance. Herein, polyhydroxylated fullerene (C 60 OH) molecules were assembled within the nanopores of a two-dimensional porphyrin-based COF (pCOF) through hydrogen-bonding interactions with the hydroxyl-functionalized 2,5-dihydroxyterephthalaldehyde (DHTA) acceptor units in the pCOF, thereby constructing a C 60 OH@pCOF photocatalytic nanoreactor featuring DHTA–C 60 OH molecular heterojunctions. Under full-light irradiation, the optimized C 60 OH@pCOF achieves a CO production rate of 40.47 μmol/(g·h) in pure water, approximately four times higher than that of pristine pCOF, along with a CO selectivity of 99%. This remarkable enhancement is mainly attributable to the introduction of C 60 OH molecules into the pCOF, which facilitates the directional transfer of photogenerated electrons from the porphyrin donor to the DHTA moieties and then to the C 60 OH acceptor. Moreover, the abundant surface hydroxyl groups on C 60 OH serve as metal-free catalytic sites that effectively activate pre-accumulated CO 2 within the nanopore-based reactor and promote the formation and conversion of key intermediates. This study provides new insights into the design and construction of porous crystalline framework-based photocatalytic nanoreactors.

Photocatalysis is an efficient strategy to deal with environmental pollution, but traditional photocatalysts commonly still suffers from rapid charge recombination, poor visible light utilization and sluggish surface catalytic kinetics. We hypothesize that the synergistic integration of oxygen vacancies with a molecular electron-acceptor can effectively modulate the electronic structure and interfacial charge transfer of wide-bandgap semiconductors. This study demonstrates a one-step controllable hydrothermal synthesis of defect-engineered Sr 0.25 H 1.5 Ta 2 O 6-x ·H 2 O and its C 60 -modified composites to boost tetracycline degradation. Among the as-synthesized composites, C 60 /Sr 0.25 H 1.5 Ta 2 O 6-x ·H 2 O-5.0% achieved the highest photocatalytic activity, exhibiting a pseudo-first-order kinetic constant of 0.02886 min⁻ 1 , which is 2.63 times higher than that of the unmodified Sr 0.25 H 1.5 Ta 2 O 6 ·H 2 O, and it also maintains high activity in various types of waste-water. This high activity is ascribed to the dual functions of C 60 as electron-trapping centers to promot charge separation and visible-light harvesting. Furthermore, radical trapping experiments confirmed that superoxide radicals (·O 2 ⁻ ) and holes (h⁺) are the dominant active species, supporting a mechanism in which photogenerated electrons drive O 2 to form ·O 2 ⁻ while holes participate in direct oxidation. Overall, our study provides a promising strategy for the rational design of high-efficiency photocatalytic systems via synergistic engineering of light harvesting and interfacial charge transfer kinetics.

Exploring metal–carbon synergies in propellants, we developed Ru-embedded fullerene (C60@Ru) additives for hydrazine fuel (HF) enhancement. Hydrothermal synthesis yielded well-defined C60@Ru nanoparticles, which were extensively characterized using electron microscopy for morphology, XRD for crystal structure, and spectroscopic methods for chemical analysis. Performance evaluations demonstrated a density increase of 0.0377 to 0.0419 g/cm3 and specific combustion energy improvement of 14.2% to 20.1% for the C60@Ru/HF composite, with completely preserved low-temperature rheological properties. DFT computations further elucidated the Ru-mediated charge transfer mechanisms driving combustion enhancement. These findings demonstrate the potential of C60@Ru as an efficient performance modifier for HF, offering new insights into C60-based energetic materials.

As new-type optoelectronic materials, organometallic halide perovskites (MAPbX 3 , X = I, Br, Cl) is an emerging solution-processable material with excellent optoelectronic performances that can be used for photodetectors and solar cells. Here, the effects of electrode materials (Au, Ag and Cu) on MAPbI 3 single crystal photodetectors are investigated. Among the three MSCPs, the one with Au electrode exhibits the lowest dark current of 0.01 μA, which indicate that the electron drift current is the dominant component of dark current in MAPbI 3 single crystals. While for the 650 nm wavelength illumination, the one with Ag electrode has largest R of 24.5 A/W and highest external quantum efficiency ( EQE ) of 4676% due to lower electron injection energy barrier at the contact. More importantly, the C 60 layer and CuPc:C 60 bulk heterojunction layer were used to modify the Au electrode respectively, a large R of 174 A/W and EQE of 33,354% is obtained by C 60 :CuPc-MSCP and C 60 -MSCP exhibits the largest PDR of 15,952 and D* of 4.5 × 10 13 Jones. These results suggest that lateral photodetectors based on MAPbI 3 single crystal modified by heterojunction buffer layer will obtain better optical performance.

Graphical Organic single-crystalline p-n junctions are grown from mixed solutions. First, C 60 crystals (n-type) form and, subsequently, C8-BTBT crystals (p-type) nucleate heterogeneously on the C 60 crystals. Both crystals continue to grow simultaneously into single-crystalline p-n junctions that exhibit ambipolar charge transport characteristics. This work provides a platform to study organic single-crystalline p-n junctions.

The effect of fullerene carbon (C60) on the tribological performance of polyimide (PI) composites was explored at different temperature conditions. The results demonstrate the addition of 1.0 wt% C60 can greatly enhance the tribological performance of PI/1.0C60. The friction coefficients and wear rates of 0.03/0.07 and 1.0 × 10 −5 /1.6 × 10 −5 mm 3 /Nm can be achieved at − 100 °C/200 °C, respectively, reducing by 86.4%/50.0% and 28.6%/30.1% compared with pure PI. It demonstrated the polymer states influenced the lubricated and loading carry capability of the sliding interfaces at different temperatures. XPS results indicated tribo-oxidation and organic-inorganic chelation reaction dominated the tribofilm growth. Moreover, molecular dynamics simulation showed the C60 enables the shear of PI easily due to the decreased intermolecular forces.

An organic ambipolar charge trapping non-volatile memory device is proposed based on tris(8-hydroxy quinoline) aluminum(Alq 3 )/ fullerene(C 60 )/pentacene double heterojunctions. The double heterojunctions were analyzed and compared with the sole heterojunction. Even though the Alq 3 /pentacene sole heterojunction shows a negative threshold voltage shift for programming under negative biasing, light illumination is required to efficiently erase. In contrast, for C 60 /pentacene sole heterojunction, the negative shift of threshold voltage is observed even with a positive erasing voltage. By combining the two trapping layers, a large memory window with fully-electrical programming and erasing is obtained. The efficient programming and erasing of the double heterojunctions structure are analyzed, sufficient electrons can be injected that enables the electrical erasing, and the negative shift of the threshold voltage under positive erasing voltage for the C 60 /pentacene structure is suppressed due to the suppression of the large built-in potential for the sole heterojunction, which can be verified by a large positive shift for the pentacene/C 60 /pentacene double heterojunctions.

The development of efficient, non-precious metal catalysts for renewable energy applications is a critical step toward sustainable power generation. This research presents and develops a simple preparation method to prepare composite catalysts based on metal phthalocyanines (MPcs) and fullerene-C 60 to improve the catalytic performance of oxygen reduction reactions (ORR) in direct lignin fuel cells ( DLFC). Electrochemical tests revealed that the FePc-C 60 catalyst demonstrated excellent catalytic performance in the ORR, with a half-wave potential (E 1/2 ) of 0.81 V, which was similar to the 0.82 V of Pt/C. Furthermore, the FePc-C 60 catalyst exhibited a near 4-electron transfer reaction mechanism, with a limiting current density of 3.9 mA cm −2 and H 2 O 2 yield below 4 %. The Tafel slope measured at 31 mV dec −1 , which was lower than the 49.6 mV dec −1 observed for the Pt/C, implying that the catalyst achieves a higher reaction rate at lower potentials. In fuel cell applications, compared to Pt/C, DLFC with FePc-C 60 as the cathode catalyst exhibited a higher maximum power density (590 mW m −2 ), surpassing Pt/C (381 mW m −2 ). This work successfully constructed an efficient and stable non-precious metal catalyst, offering a new perspective for the development of non-precious metal catalysts and high-value utilization of lignin.

The chemical modification and self-assembly capability of fullerenes offer advantageous conditions for tailoring Fe/N-doped carbon-based catalysts. However, their strong π–π stacking tendency may partially restrict metal loading and the generation of active Fe species. Therefore, how to utilize the distinctive features of fullerenes to precisely regulate and optimize Fe–N active sites along with their local coordination environment remains challenging. In this work, water-soluble C 60 (wsC 60 ) was synthesized via a facile interfacial oxidation process. The presence of –OH on the C 60 cage may strengthen its binding affinity with Fe 3+ ion and effectively modulate the incorporation of Fe/N into the C 60 -derived carbon electrodes. By varying the wsC 60 /Fe 3+ mixing ratios followed by pyrolysis under NH 3 , we obtained Fe/N-doped carbons (FeN@wsC 60 -900) with distinct Fe/N-doping states, including FeN 4 , O–FeN 4 /Fe cluster, and FeN 4 /Fe cluster. The abundant –OH in wsC 60 also promoted the formation of a highly porous network, enhancing active site accessibility. The resultant FeN@wsC 60 -900 exhibited excellent oxygen reduction reaction (ORR) activity, outperforming both conventional C 60 -derived carbons and commercial Pt/C. Structural characterizations and density functional theory (DFT) simulations revealed that the O-coordinated Fe–N 4 with adjacent Fe cluster could optimize the coordinate geometry and adsorption energies of key ORR intermediates.
