Abstract Covalent organic frameworks (COFs) are increasingly being utilized in photocatalysis due to their programmable band gaps and pore geometries. Flexible COFs currently of interest for selective sorption, though use has received little attention date. Herein, we propose a strategy modulating the flexible units facilitate efficient charge carrier separation transfer during photocatalysis. Rotational freedom linkers our led controllable local curvature, thereby optimizing optoelectronic properties boosting photocatalytic activity. One developed (COF-3) showed excellent performance uranium removal from contaminated groundwater tap water. Mechanistic studies revealed that COF-3 photocatalytically generated H2O2 under visible light irradiation water, which transformed UO22+ solid (UO2)O2·2H2O through redox pathway. The results demonstrate an effective design towards COF photocatalysts water potentially many other applications.

ABSTRACT Covalent organic frameworks (COFs) with structural versatility, tunable photophysical properties, and excellent chemical stability recyclability have been widely used as heterogeneous photocatalysts. Developing metal‐based COFs for designability unprecedented properties is highly desirable. In this paper, a new COFs‐supported photocatalyst BD Fe ‐COF embedded metallic iron (III) was successfully synthesized by the metalation reaction of FeCl 3 ·6H 2 O bipyridine‐based BD‐COF, which prepared aldehyde‐amine condensation 2,2′‐bipyridine‐5,5′‐dicarboxaldehyde 4,4′,4″,4‴‐(pyrene‐1,3,6,8‐tetrayl) tetraaniline via solvothermal method. The as‐synthesized exhibited high crystalline, stability, good properties. Moreover, photoactive employed cost‐effective catalyst in cyclocondensation o ‐phenylenediamine aldehydes. advantages current photocatalytic system included to yields, easy work‐up process, short time, together recyclability.
