The composite or hybrid of organic and inorganic materials is one of the common ways to improve the properties of photoelectric functional materials. Perylene bisimide (PBI) derivatives, as large π-conjugated organic small molecules, are a class of photoelectric functional materials with excellent performance. However, there were few reports on PBIs in the electrochromic field due to the difficulty of film-forming caused by their generally poor solubility. Here, water-soluble PBI derivatives (PDI-COOH and PCl-COOH) were synthesized. The hybrid films (ZnO@PDI-COOH/PCl-COOH) formed by the coordination bond and π–π stacking were prepared via a simple solution immersion method. Fourier transform infrared spectrometry and X-ray diffraction as well as scanning electron microscopy, and energy-dispersive spectrometry results further confirmed the formation of hybrid films. At the same time, electrochemical and spectroelectrochemical analyses revealed that the films have reversible redox activity and cathodic electrochromic properties, which can change from orange-red to purple. The ZnO@PDI-COOH hybrid film formed by coordination bonds exhibits fast switching times (1.7 s colored time and 2.6 s bleached time), good stability (retain 92.41% contrast after 2400 cycles), a low driving voltage (−0.6–0 V), and a high coloration efficiency (276.14 cm2/C). The corresponding electrochromic devices also have good electrochromic properties. On this basis, a large-area (100 mm × 100 mm) electrochromic display device with fine patterning was fabricated by using the hybrid film, and the device shows excellent reversible electrochromic performance. This idea of constructing organic–inorganic hybrid materials with coordination bonds provides an effective, energy-saving, and green method, which is expected to promote the large-scale and fine production of electrochromic materials.

Heparin is widely used to treat thrombosis because it is an effective anticoagulant. However, excessive use of heparin can lead to an increased risk of bleeding, which makes the quantitative detection of heparin very important. An amphiphilic perylene bisimide molecule (denoted PBI-9) was developed, which presented a near-infrared emission peak at 730 nm when it was aggregated. PBI-9 has been utilized in the detection of heparin, as the pyridine cation in PBI-9 binds strongly to highly sulfated heparin through electrostatic interactions. Charge neutralization triggers the self-assembly of PBI-9, which leads to an emission peak shift from 540 nm to 690 nm, corresponding to monomeric emission to excimer emission. This shift was applied for the detection of heparin. Importantly, the interaction between PBI-9 and heparin is not affected by protamine, resulting in high selectivity and minimal interference. PBI-9 is a promising tool for detecting heparin in clinical settings after excess heparin has been neutralized by protamine.

The halide perovskite/TiO 2 materials have been extensively employed for solar cells; however, they suffer from limited optoelectronic performance and stability in aqueous solution. In this manuscript, we employ a commercially available perylene dye, namely perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA), between the halide perovskite layer and the TiO 2 layer, to improve the photoelectrochemical properties of the prototypical CH 3 NH 3 PbI 3 /TiO 2 film in the aqueous solution. The incorporation of the perylene dye into the perovskite photoanode induces a photocurrent value twice as much as that offered by the bare perovskite-based film in the aqueous solution. The first-principles calculations suggest that the adsorption of the perylene dye molecule on the halide perovskite substrate is stable and the dye/perovskite interfacial structure depends on the perovskite surface terminations: for the PbI 2 -terminated perovskite surface, the perylene dye molecule interacts with the perovskite surface via the O⋯Pb contact; for the CH 3 NH 3 I-terminated perovskite surface, the perylene dye molecule interacts with the perovskite surface via the H⋯N contact. This study facilitates the fundamental understanding of the dye-sensitized halide perovskite materials for optoelectronic applications.

Various secondary structures, for example, β-sheet hydrogen bonds formed by oligopeptides exhibiting high directionality and selectivity provide a new avenue to regulate optoelectronic performances of supramolecular assemblies constructed by π-conjugated chromophores. In this work, oligopeptide-perylene diimides (AUPDIs) are synthesized to generate β-sheet strands which guide the formation of chiral supramolecular polymers with a diversity of morphologies in combination with the π–π stacking even in aqueous media. Complex morphology transitions are successfully controlled by simply adjusting the water volume fraction in the binary solvent of water and tetrahydrofuran from spherical hollow aggregates to long helical nanowires and to short nanofibers. The mechanism of the assembly changes from cooperative to the isodesmic model relying on AUPDI concentrations. This originates from the transformation in the β-sheet that regulates profoundly the arrangement of the AUPDI molecules. Prominently efficient and positive electronic sensing to triethylamine for highly helical nanowires engenders due to the highly ordered helical arrangement within the nanowires, fourfold of the short nanofibers.

A novel PDI/PS/Vis system was constructed and the photocatalytic activity of PDI with various degrees of self-assembly was explored. Perylene diimide (PDI) as photocatalysts possesses excellent charge separation efficiency and the electron injection from the PDI to persulfate (PS) can produce active species more efficiently. With the PDI/PS/Vis system, 5 mg/L bisphenol A (BPA, 50 mL) could be completely removed in 15 min with 0.5 g/L photocatalyst and 1.5 mM PS under visible light (λ>420 nm). Nearly 71.1 % of BPA was mineralized after 1 h degradation. Radical quenching tests and electron paramagnetic resonance (EPR) spectra revealed that h + , ·O 2 − , ·OH and SO 4 ·- all contributed to organics elimination with radical process. Based on the results of theoretical calculations and toxicity assessment, BPA will eventually be converted into non-toxic ring-opening products. Therefore, the highly efficient PDI/PS/Vis system has great potential for application in water environment remediation.

Photocatalytic synthesis of hydrogen peroxide (H 2 O 2 ) from H 2 O and O 2 is economically attractive, but its sluggish kinetics are challenging due to ineffective electron–hole separation. A novel photocatalyst for scalable H 2 O 2 production (SA-PDI@PDA) was constructed from self-assembled perylene diimide (SA-PDI) modified with dopamine (PDA) via electrostatic interaction. The donor–acceptor interface generates a 1.6-fold stronger interfacial electric field that enhances charge separation and enables the extraction of highly reductive electrons that increase the H 2 O 2 production rate 5.4-fold. The phenolic groups in PDA act as proton pockets, providing additional protons that accelerate H 2 O 2 production to 4873 μmol g⁻¹ h⁻¹ , with an apparent quantum yield of 12.35 % at 420 nm. This study provides valuable insight into the design of photocatalysts for enhanced and sustainable H 2 O 2 generation that is suitable for in situ sterilization and organic pollutant degradation applications.

POSS-containing polynorbornene with pendant perylene diimide (PPDI-POSS) has been synthesized, with alkyl-containing polynorbornene (PPDI-C10C8) as the reference. The supermolecular structure and photoluminescence properties were elucidated using UV-Vis absorption spectra, and one- and two-dimensional X-ray diffraction. The experimental results reveal that PPDI-C10C8 possesses a lamellar structure with close PDI stacking to meet the requirement for minimum free energy. However, the introduction of POSS cages endows PPDI-POSS with a unique hexagonal columnar structure and enhanced photoluminescence properties due to the steric hindrance of POSS cages. These results may contribute to the understanding of the structure–property relationship of the optical polymers and provide some useful information for the design of polymer materials with a controllable supramolecular structure and tunable luminescence properties.

Due to their unique physicochemical properties, the anion radical and dianion of perylene diimide derivatives(PDIs) recently attracted significant attention for organic semiconductors. However, the impact of packing structure and the radical content for carrier transport in the solid state still need to be determined. Bringing the electron-withdrawing groups is an effective strategy for enabling π−π stacking distance. Here, bay-tetrachloro-substituted PDI(B-4Cl-PDI) anion radical and dianion films were fabricated quantitatively doped with N 2 H 4 ·H 2 O. The radical contents were quantitatively calculated by absorption spectra in different doping ratios. The X-ray powder diffraction patterns showed that the anion radical presented a crystalline structure, and dianion aggregates exhibited an amorphous structure. With precise manipulation of the radical content, the anion radical aggregates and dianion aggregates showed the maximum electrical conductivity value of 0.024 and 0.0018 S/cm, respectively. The experiment results show that doping level and aggregate structure play a crucial role in electronic transport properties.

A bright white light emitting benzoperylene probe-polyethyleneimine capped quantum dot nanocomposite has been synthesized for the first time. The negatively charged benzoperylene probe with a carboxylic acid functional group tends to self-assemble in the presence of a polycation, and exhibits distinct induced excimer fluorescence. Phosphorescence emitting manganese doped zinc sulfide quantum dots (Mn-ZnS QDs) were capped with polyethyleneimine (PEI). The PEI capped Mn-ZnS QDs were used to induce the benzoperylene probe self-assembly. A bright white light emitting nanocomposite was obtained both in solution and in solid state. The white emission has Commission Internationale de l'Eclairage (CIE) coordinates of (0.33, 0.32), a color-rendering index (CRI) of 72.61 and correlated color temperature (CCT) of 5697 K. Multiple color emissions from blue to orange could also be obtained in a controllable manner via simple adjustment of the ratio of the PEI capped Mn-ZnS QDs and the benzoperylene probe. The nanocomposite displays good photo, chemical and long-term stability. A strong white light emitting LED device based on the nanocomposite was demonstrated.

The sluggish transfer of photogenerated electron-hole pairs and the high rate of carrier recombination are primary factors contributing to the suboptimal catalytic efficiency observed in organic-based photocatalysts. In this work, on the purpose of improving the photocatalytic ability of pure perylene-based micelle, rhenium bipyridine complex was introduced and the rhenium-perylene-based micelle was constructed consequently. The obtained micelle, which can achieve thorough degradation of the pollutants in the whole system within 30 min, exhibits efficient synergistic adsorption and catalysis for bisphenol A (BPA) degradation. The introduction of the metal complex exposes more active sites in the micelle. Besides, under the dual effects of photoinduced electron transfer (PIET) and metal–ligand charge transfer (MLCT), the transfer efficiency and lifetime of carriers are respectively enhanced and prolonged, which enormously increases the photocatalytic capacity of the micelle. This work will provide an insight into boosting photocatalytic properties of organic micelle materials via introducing metal active sites.

Herein, alkoxy-bridged triphenylene and perylene monoimide diester dyads (TP-Cn-PMI, n = 4, 6, and 10) were designed and synthesized, and their films were successfully prepared on the surfaces of platinum and indium tin oxide (ITO) glass electrodes by electrochemical deposition. The electrochemical deposition was carried out for different times (30, 60, 180, 300, and 600 s) in tetrahydrofuran (THF) using tetrabutylammonium hexafluorophosphate (TBAPF6) as the supporting electrolyte. The morphology, thickness, and optical properties of the films were characterized using photoluminescence (PL), scanning electron microscopy (SEM), polarized optical microscopy (POM), and atomic force microscopy (AFM). The morphology, thickness, and photocurrent density of the three dyad films were directly correlated with the prolongation of electrochemical deposition time. The results indicate that the films of the three dyads deposited for 60 s exhibited a comb-like texture with a more regular and orderly distribution, leading to higher photocurrent density. The triphenylene and perylene units of the dyads in the films predominantly align in a homeotropic (face-on) orientation. This study introduces an effective strategy for modulating the morphology, thickness, and photocurrent density of the films, thereby presenting a promising active layer material for organic solar cells.
