摘要

Two new pyrene-based fluorophores, namely 1-[4-(2, 2-diphenylvinyl) phenyl] pyrene (PVPP) and 1, 3, 6, 8-tetrakis [4-(2, 2-diphenylvinyl) phenyl] pyrene (TPVPP), were synthesized through Suzuki coupling reaction and well characterized. PVPP successfully suppresses the fluorescence quenching of pyrene units in the solid state, displaying aggregation-induced enhanced emission. Despite the same substituent, TPVPP shows a ...
