Abstract Photoresponsive materials have garnered considerable attention, particularly azo‐functionalized covalent organic frameworks (COFs), due to their unique ability undergo cis/trans isomerization under UV/visible light irradiation, making them highly promising in the field of adsorption. In this work, innovative post‐synthetic modification (PSM) approach is developed introduce azobenzene groups, resulting construction three COFs with varying degrees azo‐functionalization (ThTFB‐nN = N, n 1, 2, 3). It found that ThTFB‐nN N exhibits reversible alternating irradiation 365 and 450 nm light, degree azo content within framework, as well trans ‐ cis isomerization, can significantly influence material's properties. Notably, ‐ThTFB‐3N demonstrates highest adsorption capacity for aniline at 303.3 mg·g −1 , representing a nearly tenfold enhancement compared (30.7 ). Additionally, ThTFB‐3N shows excellent fluorescence detection capability aniline, achieving limit 22 ppb. To investigate underlying mechanisms detection, density functional theory (DFT) calculations are conducted. conclusion, work introduces novel PSM strategy incorporating photoresponsive units, leading multifunctional material substantial potential detection.
