摘要
Environmental pollution is one of the most severe problems facing today,including water pollution and the greenhouse effect.Therefore,developing materials with high-efficiency dyes adsorption and CO_(2)uptake is significant.Covalent organic frameworks(COFs),as a burgeoning class of crystalline porous polymers,present a promising application potential in areas related to pollution regulation due to their exciting surface properties.Herein,we report a 3D COF with a high specific surface area(BET about 2072 m^(2)/g)by utilizing tetrahedral and rectangle building blocks connected through[4+4]imine condensation reactions to synthesize.The obtained COF not only can separate dyes from water effectively but also shows a remarkable CO_(2)uptake capacity.This research thus provides a promising material to remove dyes and adsorb CO_(2)in environmental remediation.
