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 and N,N,N′,N′-tetraphenylbenzidine catalyzed by methanesulfonic acid.

A series of novel triazine-based conjugated microporous polymers were constructed via Friedel–Crafts polymerization.

A covalent triazine-based framework with a tetraphenylthiophene (TTPT) backbone was prepared by the AlCl3 catalyzed Friedel–Crafts reaction of commercially available material 2,4,6-trichloro-1,3,5-triazine with tetraphenylthiophene in dichloromethane.
