Covalent organic frameworks (COFs) show potential as photocatalysts for harnessing solar energy, primarily because of their adjustable band gap, which enhances ability to harvest light energy. However, efficiency is frequently hampered by inadequate charge transfer and fast recombination. In this work, we integrated a donor-acceptor pair into the 2D COF material enhance reduce recombination, thereby improving overall photoactivity. The (OML-4) was synthesized through polycondensation 4',4‴,4‴″,4‴‴'-(ethene-1,1,2,2-tetrayl)tetrakis(([1,1'-biphenyl]-4-carbaldehyde)) (ETBC) linker serving donor 4,4',4″-(1,3,5-triazine-2,4,6-triyl)trianiline (TAPT) acting acceptor. This imine-linked shows photocatalytic activity toward benzylic amine oxidation in presence visible formation aldehyde molecules an aqueous medium. also investigated HCl gas sensing behavior based on protonation imine linkage triazine unit present material. exhibits exceptionally good sensitivity up ppm level naked eye detection changing color from yellow red turning back ammonia vapor, showing reversible recyclable nature COF.
