Benzothiadiazole functionalized D–A type covalent organic frameworks for effective photocatalytic reduction of aqueous chromium(<scp>vi</scp>)

Abstract

Photocatalytic covalent organic frameworks were facilely constructed <italic>via</italic> the integration of alternative donor–acceptor units into the 2D extended and crystalline scaffolds, which exhibit excellent photodegradation efficiency toward aqueous Cr(<sc>vi</sc>).
