Recent Advances in the Use of Covalent Organic Frameworks as Heterogenous Photocatalysts in Organic Synthesis

Advanced Materials, Год журнала: 2022, Номер 35(24)

Опубликована: Дек. 23, 2022

Abstract Organic photochemistry is intensely developed in the 1980s, which nature of excited electronic states and energy electron transfer processes are thoroughly studied finally well‐understood. This knowledge from molecular organic can be transferred to design covalent frameworks (COFs) as active visible‐light photocatalysts. COFs constitute a new class crystalline porous materials with substantial application potentials. Featured outstanding structural tunability, large porosity, high surface area, excellent stability, unique photoelectronic properties, potential candidates various research areas (e.g., photocatalysis). review aims provide state‐of‐the‐art insights into COF photocatalysts (pristine, functionalized, hybrid COFs) for transformations. The catalytic reaction mechanism COF‐based influence dimensionality crystallinity on heterogenous photocatalysis performance also discussed, followed by perspectives prospects main challenges opportunities future
