摘要

This work reviews recent advances in sp

-carbon-conjugated organic frameworks with ethylene-bonded linkers for photocatalysis

outlines the design principles and synthesis methods of sp

c-COFs and systematically summarizes various strategies for enhancing photocatalytic performance

and finally discusses challenges and future prospects for sp

c-COFs in practical photocatalytic applications.

Abstract

-Carbon-conjugated organic frameworks (sp

c-COFs) are a class of porous crystalline polymers constructed through the ordered linkage of building blocks

via

vinylene bonds. Because of their high specific surface area

extended planar

-conjugation

and remarkable stability

c-COFs are regarded as highly promising novel photocatalysts. This review begins by introducing the design principles and synthetic methods for sp

c-COFs. Subsequently

various strategies for enhancing photocatalytic performance have been summarized

including designing donor-acceptor (D-A) structures

crafting charged frameworks

developing heterojunctions

and modifying covalent organic frameworks (COFs) pore channels. We then elaborate on the applications of sp

c-COFs in photocatalytic H

production

roduction

reduction

organic transformation reactions

and uranium extraction from seawater. Finally

the challenges and future prospects of sp

c-COFs for practical applications in photocatalysis were discussed.
