Abstract
AbstractCovalent organic frameworks (COFs) exhibit excellent characteristics in the optoelectronic and photocatalytic areas. The broad demand for highly efficient flexible clothes enhances the investigation of multifarious COFs materials. Currently, COFs have materialized as future generation flexible clothes layered materials with previously designed π‐π stacking skeletons and extremely efficient ordered structures, which are more fascinated for countering their photocatalytic characteristics. Still, COFs are generally formed as solid materials because of direction‐dependent growth which make them unpredictable to integrate into flexible clothes. Here, by choosing tetraamino‐benzoquinone (T) and N,N'‐di‐(4‐benzoic acid)‐perylene‐3,4,9,10‐tetracarboxylic acid diimide (BP) monomers with photocatalytic activity, ornately designed sun‐light‐responsive COFs with well‐ordered donor and acceptor moieties are in situ synthesized on flexible activated carbon cloth (fACC), eventually forming TBPCOF‐fACC structures. Ultra‐responsive photocatalyst is fruitfully fabricated with the TBPCOF‐fACC structure and showed an excellent selective C‐S arylation performance with high yields (99 %) at ambient temperature. The research presents new plans for constructions of advanced light harvesting functional flexible clothes with programmable COFs material, covering the technique for a creation of highly improved applications in photocatalytic and various areas. The TBPCOF‐fACC based humidity sensor shows the average sensitivity as 1.58 MΩ/%RH along with calculated response and recovery time as 15 s and 55 s respectively. The sensor has 96.20 % repeatability and shows long term stability.
