| Abstract: | Covalent organic frameworks(COFs) with high specific surface area, regular structure, and modi-fiable pore channels, are crystalline porous organic polymers and have been widely used in various fields. Azobenzene derivatives with light isomerization characteristics are important stimulus-responsive materials. Herein we report a method of postsynthetic modification for the preparation of photothermal responsive azobenzene-functionalized COF, denoted as JUC-501(JUC=Jilin University China), which based on introducing small azobenzene molecules into the channels of COF(JUC-500). Under ultraviolet irradiation and heating conditions, the COF with azobenzene in the pores will undergo reversible cis-trans isomerization reaction and exhibits excellent reversible capture and release properties for methyl orange(MO). |
