Abstract Organic room temperature phosphorescence (RTP) materials have become a hot topic in the field of luminescence wherein crystalline porous organic frameworks (metal–organic (MOFs), hydrogen‐bonded (HOFs), covalent (COFs))‐based RTP are receiving considerable attention. Beyond all doubt, frameworks‐based perfectly integrate advantages and materials. This review provides timely brief outline for development including construction strategy MOFs/HOFs/COFs‐based their performance as well potential applications. Moreover, conclusion outlook also discussed to present challenges prospects further high‐performance

Robust Thiazole‐Linked Covalent Organic Frameworks with Post‐Modified Azobenzene Groups: Photo‐Regulated Dye Adsorption and Separation

Abstract Due to the intrinsic porosity and photo‐regulated pore environment, azobenzene (Azo) functionalized covalent organic frameworks (COFs) show great potential for contaminant removal. However, stability degree of functionality COFs greatly affect subsequent adsorption capacity selectivity. Herein, a highly stable thiazole‐linked COF containing phenolic hydroxyl groups (OH‐COF) is constructed by using 4,4′,4′‐(1,3,5‐triazine‐2,4,6‐triyl)trianiline 2,5‐dihydroxyterephthalaldehyde in presence sulfur, which shows high crystallinity specific surface. Azo‐functionalized ((Azo) x ‐COFs) are prepared grafting different amounts onto OH‐COF through post‐modification, whose aperture conveniently tuned grafted amount. The size ‐COFs also can be reversibly adjusted under UV visible light irradiation without affecting crystallinity. Appropriate amount Azo‐grafted 0.1 ‐COF possessed (1216.93 mg g −1 ) Congo red (CR). While 1.0 CR significantly increased 2.9 times reach 1489.96 after irradiation. selectively separate dye molecules with sizes based on size, showing excellent reversibility reusability. As such, ability photo‐regulate interception highlights their significance functioning as smart porous nanomaterials pollutant removal water purification.
