A nitrogen-rich fluorescent conjugated microporous polymer with triazine and triphenylamine units for high iodine capture and nitro aromatic compound detection

Abstract

A new kind of nitrogen-rich fluorescent conjugated microporous polymer TTPB was synthesized via a Friedel–Crafts reaction of 2,4,6-trichloro-1,3,5-triazine (TCT) and N,N,N′,N′-tetraphenylbenzidine (TPB) catalyzed by methanesulfonic acid. Having structural features of an expanded conjugated area, N-rich, twisted structure, and microporosity in polymer networks, TTPB showed excellent, efficient, reversible ultrahigh absorption performance for iodine vapour with an uptake of up to 4.43 g g−1, which is the highest value reported to date for CMPs. Furthermore, fluorescence study indicated that TTPB exhibits high sensitivity to electron-deficient nitrobenzene explosives via fluorescence quenching.
