The synthesis of tetraarylethylene-based conjugated polymers for the application of fluorescence sensing towards nitroaromatics

Abstract

Using the Suzuki cross-coupling method, the tetraarylethylene-based conjugated polymers PT-F and PT-Cz were synthesized by reacting 9-(dibromomethylene)-9H-thioxanthene with (9,9-dihexyl-9H-fluorene-2,7-diyl)diboronic acid and 9-heptyl-3,6-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9H-carbazole ester, respectively. PT-F and PT-Cz exhibit significant aggregation-induced...
