摘要: A novel multifunctional molecule BTE-CNPH was designed and synthesized by connecting 2-(3′,5′-bis(trifluoromethyl)-biphenyl-4-yl)-2-cyanovinyl group to both side of the bisthienylethene (BTE), which exhibited excellent aggregation-induced emission (AIE) bistable photochromism. High-contrast (>60) reversible fluorescence switching achieved in 1D nanowires, solid also a polymethyl methacrylate (PMMA) film loaded with 1% under alternative irradiation 365 nm visible light. Interestingly, nanowire-like assembly morphology aqueous tetrahydrofuran (THF) solution specific concentration observed translate into amorphous pieces gradually upon prolonged 365 nm, accompanying photo-tunable AIE emission.
