Solar-driven photocatalysis is a promising green technology for wastewater treatment. Molybdenum disulfide (MoS 2 ) is a highly efficient visible-light photocatalyst. However, due to the rapid recombination of photoinduced electron-hole (e - -h + ) pairs, its photocatalytic activity is severely limited, thereby hindering its practical application. To solve this problem, a novel MoS 2 -3,4,9,10-perylene tetracarboxylic acid (MoS 2 -PTCDG) heterojunction was synthesized via a hydrothermal method. In this composite, PTCDG nanosheets are embedded in the interlayer spaces of three-dimensional flower-like MoS 2 nanospheres, forming an organic–inorganic heterostructure. This design not only improves the separation efficiency of photogenerated e - -h + pairs, but also the hydrophilic terminal carboxyl groups on PTCDG can serve as adsorption sites for Cr(VI) pollutants. The MoS 2 -PTCDG composite demonstrates exceptional photocatalytic activity and stability in degrading Cr(VI) under simulated sunlight, achieving a reaction rate constant 2.5 times higher than that of pure MoS 2 . This study highlights the potential of rationally designed organic–inorganic heterostructures to overcome the limitations of traditional MoS 2 -based photocatalysts, thus offering new insights into the development of high-performance photocatalytic materials for environmental remediation.

Organic electroactive compounds can be applied as alternative cathodes in rechargeable zinc ion batteries (ZIBs) instead of using inorganic cathode materials with low stability or high toxicity. However, many reported organic ZIB cathodes have some limitations, which are their tedious synthesis processes and low yields. In this work, perylene diimide-ethylenediamine/carbon black (PDI-EDA/CB) composites are prepared with a high yield of over 88% under mild conditions via a solution-based processing method. As the organic cathodes in aqueous ZIBs, the PDI-EDA/CB composites have a high specific capacity of 118.0 mA h g −1 at 0.05 A g −1 ; this capacity can be maintained as 95.0 mA h g −1 even at a high current density of 5.00 A g −1 . Also, PDI-EDA/CB has good cycling stability by reserving 70.5% of its initial capacity after 1500 charge-discharge cycles at 1.00 A g −1 , outperforming many recently reported ZIB cathodes. As disclosed by the structural and electrochemical characterization of PDI-EDA/CB, its excellent electrochemical performance is due to the zinc ion storage mechanism of PDI-EDA and the solution-based fabrication method.

Rational design of semiconductor molecule structure is of significant importance for achieving the multifunctional photocatalysis. Herein, three end/bay-substituted perylenediimide (PDI) molecules, including bis(N-carboxymethyl) perylenediimide (H 2 PDI), 1,7-dibromo-substituted H 2 PDI (2Br-H 2 PDI) and 1,6,7,12-tetraether-substituted H 2 PDI (4CH 3 CH 2 O-H 2 PDI), are synthesized for photocatalytic oxygen evolution (POE) and oxygen reduction reaction (ORR). One-dimensional H 2 PDI nanorods, two-dimensional 2Br-H 2 PDI nanosheets, and zero-dimensional 4CH 3 CH 2 O-H 2 PDI nanoparticles are obtained. Under visible light, 4CH 3 CH 2 O-H 2 PDI as photocatalyst (5.31 mmol·g −1 ·h −1 ) exhibits the 1.8-times and 20-times POE rate of 2Br-H 2 PDI (2.93 mmol·g −1 ·h −1 ) and H 2 PDI (0.26 mmol·g −1 ·h −1 ) with AgNO 3 as sacrificial agent. Additionally, the POE rate can be further improved to 9.34 mmol·g −1 ·h −1 with the Co 2+ doping of 4CH 3 CH 2 O-H 2 PDI. With isopropanol as sacrificial agent, the H 2 O 2 evolution rate of 657.4 μM·g −1 ·h −1 can be also achieved via photocatalytic ORR with 4CH 3 CH 2 O-H 2 PDI as catalyst, which is ∼3 and ∼4 times those of 2Br-H 2 PDI (220.8 μM·g −1 ·h −1 ) and H 2 PDI (160.0 μM·g −1 ·h −1 ), respectively. Especially, in the O 2 - or air- saturated aqueous solution without sacrificial agent, the H 2 O 2 rate of 273.1 or 112.7 μM·g −1 ·h −1 can be also achieved. This work provides a promising way to design the PDI-based multifunctional photocatalysts.

To exploit the noble-metal-free, highly efficient and broad-spectrum responsive photocatalyst of perylenetetracarboxylic diimide (PDI), a self-assembled PDI nanowire is loaded on the surface of a graphite-like carbon nitride (g-C 3 N 4 ) nanosheet and forms an all-organic supramolecular 1D/2D heterogeneous g-C 3 N 4 /PDI with broad-spectrum responsiveness (254–700 nm), which can improve the absorption efficiency of solar energy. In the g-C 3 N 4 /PDI system, the π–π conjugated bond in the g-C 3 N 4 /PDI can accelerate the photoinduced charge carrier transfer. On the other hand, the interlaced band structure between the g-C 3 N 4 and PDI and the Z-scheme pathway of the carriers leads to the spatial separation of redox reaction sites. Therefore, the g-C 3 N 4 /PDI photocatalyst reaches strong redox ability in the photocatalytic process. In detail, the photocatalytic phenol degradation of g-C 3 N 4 /PDI (0.837 h −1 ) is enhanced 2.67 and 9.19 times higher as the pure PDI and g-C 3 N 4 , respectively, under the full spectra. Meanwhile, the H 2 evolution activity of the g-C 3 N 4 /PDI (1649.93 μmol g −1 h −1 ) is 2.03 times higher than g-C 3 N 4 nanosheet (814.03 μmol g −1 h −1 ).

For some small biomolecules with simple structures, it is difficult to achieve rapid detection because they lack strong interactions with probes. To solve this problem, we have developed an approach based on perylene diimide derivatives combining an in-situ pre-modification technique. In this strategy, the nucleophilic reaction of o-phthalaldehyde (OPA) was used to enhance the non-covalent interactions between the analyte and probe. This method was utilized for sensing glutathione (GSH) and spermidine (SPD) and had the characteristics of fast response, wide detection range, and high selectivity. Moreover, it has been validated with real samples and the detection mechanism was investigated systematically. To the best of our knowledge, this is the first attempt to apply perylene diimide derivatives to the detection of some biological small molecules by an in-situ pre-modification method.

The development of efficient and environmentally friendly photocatalysts is crucial for addressing global energy and environmental challenges. Perylene diimide, an organic supramolecular material, holds great potential for applications in mineralized phenol. In this study, through the integration of different mass ratios of unmodified perylenimide (PDI-NH) into the self-assembly of amino acid-substituted perylenimide (PDI-COOH), a novel supramolecular organic heterojunction (PDICOOH/PDINH) was fabricated. The ensuing investigation focuses on its visible-light mineralized phenol properties. The results show that the optimal performance is observed with a composite mass fraction of 10%, leading to complete mineralization of 5 mg/L phenol within 5 h. The reaction exhibits one-stage kinetics with rate constants 13.80 and 1.30 times higher than those of PDI-NH and PDI-COOH, respectively. SEM and TEM reveal a heterogeneous interface between PDI-NH and PDI-COOH. Photoelectrochemical and Kelvin probe characterization confirm the generation of a built-in electric field at the interface, which is 1.73 times stronger than that of PDI-COOH. The introduction of PDI-NH promotes π-π stacking of PDI-COOH, while the built-in electric field facilitates efficient charge transfer at the interface, thereby enhancing phenol decomposition. The finding demonstrates that supramolecular heterojunctions have great potential as highly effective photocatalysts for environmental remediation applications.

As an important biological indicator, the abnormity of the lysozyme level is closely related to many diseases. Herein, we devise a novel ratiometric fluorescence aptasensor for lysozyme based on the controllable excimer formation of a perylene probe, N, N′-bis(6-caproic acid)-3,4:9,10-perylene diimide (PDI) induced by cationic silver nanoparticles (Ag NPs). Binding of lysozyme aptamer with multiple phosphate groups to cationic Ag NPs strongly hinders the formation of excimer, yielding intense monomer fluorescence of PDI probe. With the introduction of lysozyme, the adsorption of aptamer on the surface of Ag NPs will be weakened owing to the specific interactions between aptamer and lysozyme, which greatly facilitates the excimer formation of PDI. Based on the monomer-excimer transition triggered by lysozyme, ratiometric fluorescence aptasensor for lysozyme can be established. A good linear relationship between the ratio of monomer intensity to excimer intensity and the logarithm of lysozyme concentration was obtained in the range of 0.25–15 nM, and as few as 0.25 nM lysozyme could be easily detected. Moreover, excellent selectivity for lysozyme detection and satisfactory results in real sample analysis were also achieved. This work provides an innovative platform for the construction of simple, label-free ratiometric fluorescence sensors towards a wide range of analytes based on perylene probe.

Four novel mesogenic dyads consisting of a hexa(alkoxy)triphenylene donor that was linked to a perylene tetracarboxylic esters acceptor by the bridges (O–(CH2)2–O), (O–(CH2)6–O), (O–(CH2)10–O) and (O–(CH2)12–O), had been synthesized. Their structures were characterized by 13C and 1H nuclear magnetic resonance (NMR), infrared spectroscopy (IR) and elemental analysis (EA). The experimental results of cyclic voltammetry and UV/Vis showed the aliphatic linkage of the donor–acceptor dyads preserved the genuine electrochemical behaviors and light absorption properties of the donor and acceptor units, and the energy level difference between the HOMO of the donor and the LUMO of the acceptor is about 1.94 eV. The differential scanning calorimetry (DSC) traces and polarizing optical microscopy (POM) textures confirmed that all dyads had mesophase. When excited at 443 nm, fluorescence quenching process of the acceptor unit was ascribed to a intramolecular ground-state charge transfer from the donor to it. And the fluorescence quenching varying with the bridge lengths were understood by Dexter-type energy transfer theory. These behaviors of photoinduced intramolecular charge transfer and forming columnar liquid crystal phase made these dyads candidates of new active materials in organic solar cells.

How to design and optimize the single-molecule structure of perylene diimide derivatives (PDIs) to obtain high-performance photocatalysts is one of the challenges facing the current research field of PDIs photocatalysis. In this article, we regulate the π-π self-assembly stacking and optoelectronic properties of PDIs by changing the type and position of substituents on the amide site. The PDI-PBA photocatalyst with excellent performance was obtained from seven types of PDIs supramolecular materials. Theoretical calculations and optoelectronic performance tests have shown that PDI-PBA has good crystallinity and maximum dipole moment, resulting in its maximum built-in electric field, effectively promoting the separation and transport of photo-generated carriers. The transient absorption spectra further indicate that photogenerated electrons and holes of PDI-PBA have outstanding separation efficiency and ultra-long lifetime. In the batch reactor, PDI-PBA can degrade almost 100% acetaminophen within 60 min. In the dynamic cycling system with a surface hydraulic load of 14.56 L/(m 2 ·h), the efficiency of PDI-PBA photocatalytic degradation of acetaminophen can reach 84%. PDI-PBA can also effectively degrade phenol, levofloxacin, and ciprofloxacin. This work provides a successful example for the design of novel and efficient PDIs supramolecular materials, and lays the foundation for the application of PDIs photocatalysts in practical wastewater treatment.

Electrochemiluminescence (ECL) is a light-emitting process that occurs via an annihilation reaction among energetic radical intermediates, whose stabilities determine the ECL efficiency. In this study, a ligand-dimerized metal–organic framework (MOF) with ultrastable anion radical is designed as an efficient nanoemitter for self-accumulated ECL. Due to the nonplanar structure of perylene diimide (PDI) derivate, two PDI ligands in the framework form a J-dimer unit with a vertical distance of ∼5.74 Å. In cathodic scanning, the ligand-dimerized MOF demonstrates three-step ECL emissions with a gradual increase in ECL intensity. Unlike the decrease in the PDI ligand, the self-accumulated ECL of the MOF was observed with 16.8-fold enhancement due to the excellent stability of radical intermediates in frameworks. Electron paramagnetic resonance demonstrated the ultrastability of free radicals in the designed frameworks, with 82.2% remaining even after one month of storage. Density functional theory calculations supported that PDI dimerization was energetically favorable upon successive electron injection. Moreover, the ECL wavelength is 610 nm, corresponding to the emission of excited dimers. The radical-stabilized reticular nanoemitters open up a new platform for decoding the fundamentals of self-accumulated ECL systems.

Organic–inorganic hybrid materials have been extensively used in sensing, bioimaging, and optoelectronics. In particular, photosensitive organic–inorganic hybrid nanomaterials with a high aspect ratio are widely used in flexible electronics and light-emitting displays due to their efficient charge transfer properties. Herein, we report the fabrication of organic–inorganic hybrid nanofibers with excellent charge transfer performance. The nanofibers consisting of perylene imide (denoted as PDI), polyoxometalate (POM, H3PW12O40), and surface-active ionic liquid (IL, [N-C12, N′-COOH-Im]Br) are obtained through a bottom-up hierarchical self-assembly process. First, POM and IL are utilized to construct nanoparticles (POM-IL) via ionic self-assembly. Then, the PDI/POM-IL nanofibers are constructed by self-assembly of POM-IL complexes and PDI via a rapid solution dispersion method. The formation of PDI/POM-IL nanofibers is confirmed by multielemental energy-dispersive spectroscopy (EDS) measurements. Notably, the results of small-angle X-ray scattering (SAXS) and X-ray diffraction (XRD) indicate that the main structures of PDI/POM-IL nanofibers and PDI fibers are similar. In addition, photoluminescence quenching of the PDI/POM-IL nanofibers is observed, testifying a valid charge transfer between PDI and POM-IL complexes. It is confirmed by various characterization methods such as fluorescence, time-resolved photoluminescence, quantum yield, and photodegradation. The results indicate that the bottom-up hierarchical self-assembly is a valid method for fabricating organic–inorganic hybrid nanomaterials with great potential in sensing, bioimaging, and optoelectronics.
