Anthraquinones-based photocatalysis: A comprehensive review

Environmental Science and Ecotechnology, Journal Year: 2024, Volume and Issue: 22, P. 100449 - 100449

Published: July 5, 2024

In recent years, there has been significant interest in photocatalytic technologies utilizing semiconductors and photosensitizers responsive to solar light, owing their potential for energy environmental applications. Current efforts are focused on enhancing existing photocatalysts developing new ones tailored uses. Anthraquinones (AQs) serve as redox-active electron transfer mediators photochemically active organic photosensitizers, effectively addressing common issues such low light utilization carrier separation efficiency found conventional semiconductors. AQs offer advantages abundant raw materials, controlled preparation, excellent capabilities, photosensitivity, with applications spanning the energy, medical, sectors. Despite utility, comprehensive reviews AQs-based systems contexts lacking. this review, we thoroughly describe photochemical properties of photocatalysis, particularly key challenges like clean production, antibacterial action, pollutant degradation. However, face limitations practical due electrical conductivity solubility-related secondary contamination. To mitigate these issues, design synthesis graphene-immobilized highlighted a solution enhance Additionally, future research directions proposed deepen understanding AQs' theoretical mechanisms provide wastewater treatment. This review aims facilitate mechanistic studies improve technologies.

Pyrene‐Alkyne‐Based Conjugated Porous Polymers with Skeleton Distortion‐Mediated •O2‐ and 1O2 Generation for High‐Selectivity Organic Photosynthesis

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: unknown

Published: May 31, 2024

Abstract Reactive oxygen species (ROS) play a crucial role in determining photocatalytic reaction pathways, intermediate species, and product selectivity. However, research on ROS regulation polymer photocatalysts is still its early stages. Herein, we successfully achieved series of modulations to the skeleton Pyrene‐alkyne‐based (Tetraethynylpyrene (TEPY)) conjugated porous polymers (CPPs) by altering linkers (1,4‐dibromobenzene (BE), 4,4′‐dibromobiphenyl (IP), 3,3′‐dibromobiphenyl (BP)). Experiments combined with theoretical calculations indicate that BE‐TEPY exhibits planar structure minimal exciton binding energy, which favors dissociation followed charge transfer adsorbed O 2 produce ⋅O − . Thus shows optimal activity for phenylboronic acid oxidation [3+2] cycloaddition. Conversely, BP‐TEPY significantly distorted. Its conjugation decreases, intersystem crossing (ISC) efficiency increases, makes it more prone resonance energy generate 1 Therefore, displays best [4+2] cycloaddition thioanisole oxidation. Both above reactant conversion selectivity exceed 99 %. This work systematically reveals intrinsic structure–activity relationship among CPPs, excitonic behavior, selective generation ROS, providing new insights rational design highly efficient CPPs photocatalysts.
