The synthesis of conjugated microporous polymers via Friedel–Crafts reaction of 2,4,6-trichloro-1,3,5-triazine with thienyl derivatives for fluorescence sensing to 2,4-dinitrophenol and capturing iodine

The preparation of 3,4‐ethylenedioxy thiophene (EDOT)‐based conjugated microporous polymers by direct arylation polymerization and fluorescence‐sensing nitro‐aromatic compounds and iodine

“…6,12,13 Conventional C C coupling syntheses of thiophene-based CMPs have been put into effect by transition-metal catalyzed reactions, for instance, Sonogashira-Hagihara reactions, [8][9][10][14][15][16][17][18][19][20] Suzuki-Miyaura reactions, 18,[21][22][23] and Stille reactions. 11,24 Other coupling reactions are also widely used in the preparation of thiophene-based CMPs, for example, Schiff-base reversible condensation, [25][26][27][28] Friedel-Crafts arylation, 29,30 hypercrosslinked, 31,32 nucleophilic substitution, 33 trimerization of cyano 34,35 reactions. However, most of these reactions involve multiple steps of the functionalization of building blocks.…”
