ACS Catalysis, Journal Year: 2025, Volume and Issue: 15(3), P. 1829 - 1840

Published: Jan. 17, 2025

Perylene diimides (PDIs) and their derivatives represent a kind of most promising photocatalytic materials due to strong visible light absorption, ease functionalization, excellent thermal/photostability, as well tunable electronic structures energy levels. However, several challenges persist in the development PDI photocatalysts, including low electron–hole separation efficiency, slow charge transfer, rapid carrier recombination. In this perspective, we focus on enhancing performance photocatalysts through molecular design. We provide comprehensive overview various improvement strategies: (1) precise modulation dipole moments by altering polarity side chains strengthen built-in electric field, (2) utilization steric hindrance noncovalent interactions construct nanoscale, highly ordered supramolecular nanostructures, (3) modification perylene core adjust levels increase number active sites, (4) integration with semiconductors or metals form composite systems that enhance interfacial field create extensive delocalized channels, (5) selection suitable linker groups build polymer large moments. These strategies can facilitate migration photogenerated carriers eventually boosting efficiency. The relationship between structure performance, particularly context degradation water splitting, is examined detail. Finally, future prospects are thoroughly discussed.

Organophotocatalytic Mechanisms: Simplicity or Naïvety? Diverting Reactive Pathways by Modifications of Catalyst Structure, Redox States and Substrate Preassemblies

ChemCatChem, Journal Year: 2023, Volume and Issue: 15(11)

Published: Feb. 21, 2023

Abstract Photocatalysis is a powerful tool to assemble diverse chemical scaffolds, yet bottleneck on its further development the understanding of multitude possible pathways when practitioners rely only oversimplified thermodynamic and optical factors. Recently, there growing number studies in field that exploit, inter alia , kinetic parameters organophotocatalysts are synthetically more programmable terms their redox states opportunities for aggregation with target substrate. Non‐covalent interactions play key role enables access new generation reactivities such as those open‐shell organophotocatalysts. In this review, we discuss how targeted structural modifications influence organophotocatalytic mechanisms together underlying principles. We also highlight benefits strategies preassembly static quenching overcome common reactivity issues (e. g., diffusion rate limits energetic limits).

Molecule Dipole and Steric Hindrance Engineering to Modulate Electronic Structure of PTCDA/PTA for Highly Efficient Photocatalytic Hydrogen Evolution and Antibiotics Degradation

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 34(17)

Published: Dec. 22, 2023

Abstract Insufficient charge separation and slow exciton transport severely limit the utilization of perylene‐plane‐based organic photocatalysts. Herein, a novel PTCDA/PTA (perylene‐3,4,9,10‐tetracarboxylic dianhydride/perylenetetracarboxylic acid) is successfully prepared for first time by in situ crystallization PTA on surface PTCDA through π – interaction. The loading with 8%PTCDA showed optimum photocatalytic performance. H 2 evolution rate reached 45.06 mmol g −1 h , which 1.93‐fold 4506.00‐fold higher than that pure PTCDA. Meanwhile, it also exhibited excellent antibiotics photodegradation activities, both removal efficiency tetracycline hydrochloride (TC‐HCl) ofloxacin (OFL) are more over 90% within 30 min. By modulating structures perylene plane, steric hindrance internal dipole moments can be precisely tuned. These lead to change stacking mode, promoting degree formation strong electric field, while improved activity. Excited state density functional theory (DFT) calculations unveil redistribution electron‐hole pairs, obeys type II mechanism. proposed mechanism determined liquid chromatography‐mass spectrometry (LC‐MS). Besides, toxicities degradation products evaluated. work provides useful strategy design high‐performance multifunctional photocatalysts toward water remediation energy production.
