A novel fluorophore TPE-HBT was designed based on the intersection of tetraphenylethene (TPE) and 2-(2′-hydroxyphenyl)benzothiazole (HBT). Owing to the synergistic effect of aggregation-induced emission (AIE) and excited-state intramolecular proton transfer (ESIPT) mechanisms, this fluorophore exhibits excellent performance with a high solid-state fluorescence quantum yield (ΦF = 0.97) and a large Stokes shift (>200 nm). Moreover, its simple modification with the 2,4-dinitrobenzenesulfonyl group makes it suitable for biothiol imaging.

基于AIE和ESIPT机理耦合的新型荧光团及其在生物硫醇成像中的应用

基于四苯乙烯(TPE)和2-(2'-羟苯基)苯并噻唑(HBT)的交点,设计了一种新型的荧光团TPE-HBT。由于聚合引起的发射的(AIE)和激发态分子内质子转移(ESIPT)机制,该荧光团表现出具有高固态荧光量子产率(性能优良的协同效果Φ ˚F = 0.97)和大的斯托克斯频移(> 200 nm)。此外,其简单地用2,4-二硝基苯磺酰基进行修饰使其适用于生物硫醇成像。
