Abstract A novel perylene diimide (PDI‐ C 8 SAc) was used as a modifier for carbon felt electrode (CFE) and prepared modified applied dopamine detection. Obtained electrochemical current almost 15‐fold higher compared to plain CFE. Also cathodic shift in the peak potential obtained indicating electrocatalytic effect of developed sensor. Under optimized experimental conditions, linear range observed between 1–100 μM with limit detection value 0.084 ( n =3). The fabricated sensor successfully utilized determination based medicines.

Single perylene diimide (PDI) used as a non-fullerene acceptor (NFA) in organic solar cells (OSCs) is enticing because of its low cost and excellent stability. To improve the photovoltaic performance, it vital to narrow bandgap regulate stacking behavior. address this challenge, we synthesize soluble perylenetetracarboxylic bisbenzimidazole (PTCBI) molecules with bulky side chain at bay region, by replacing widely "swallow tail" type alkyl chains imide position PDI planar benzimidazole structure. Compared molecules, PTCBI exhibit red-shifted UV-vis absorption spectra larger extinction coefficient, one magnitude higher electron mobility. Finally, OSCs based on PTCBI-type NFA, namely MAS-7, champion power conversion efficiency (PCE) 4.34%, which significantly than that corresponding PDI-based highest PCE PTCBI-based reported. These results highlight potential derivatives NFAs OSCs.

Abstract Curved perylene diimides fused with seven‐membered rings have been synthesized using a regioselective bay‐functionalization method and Pd‐catalyzed intramolecular C−H/C−Br coupling reaction. X‐Ray analysis temperature‐dependent NMR spectroscopy revealed the curved molecular structure certain degree of conformational flexibility. The expanded π‐conjugation altered electronic properties while retaining intrinsic parent diimide. Despite absence solubilizing N ‐substituents, showed sufficient solubility for application in solution‐processed organic photovoltaic devices. devices superior performance power conversion efficiency up to 2.76% due suppressed charge recombination. Our detailed investigations suggest that introduction enables removal bulky which is an effective way achieve thin‐film morphology suitable photoelectric conversion.

Abstract Solubility enhancement is a key issue for developing the perylene diimide‐based functional materials. Introduction of curved structure proved an effective solubilizing method without employing steric repulsion. In this work, wavily diimides were developed as new family highly soluble diimides. Moreover, their conformational dynamics, aggregating properties, electronic and photovoltaic performances thoroughly examined in comparison to previously reported isomer exhibiting arched curvature. The waved demonstrated heightened rigidity greater propensity aggregation compared isomer, likely attributed its more planar structure. Each benzoxepin unit played role cancelling out curvature on opposite side. While difference molecular did not cause significant alterations photophysical electron‐accepting we identified that modulation controlling morphology photoelectric conversion layer.

While spin-orbit coupling does not play a decisive role in the photophysics of unsubstituted perylene diimides (PDI), this changes dramatically when two phenylselenyl or phenyltelluryl substituents were attached to PDI bay positions. In series PhO-, PhS-, PhSe-, and PhTe-substituted PDIs we observed strongly decreasing fluorescence quantum yield as consequence increasing intersystem crossing (ISC) rate, measured by transient absorption spectroscopy with fs- ns-time resolution well broadband upconversion. Time-dependent density functional calculations suggest due internal heavy-atom effect reason for fast ISC. case selenium derivative found significant singlet oxygen sensitization via triplet state.
