Three new tetraphenylethylene based oligomers bearing triphenylethylene moiety were synthesized utilizing Suzuki coupling reaction and their aggregation-induced emission properties were studied. They show excellent solubility in common organic solvents and emit light in blue region (440−504 nm). AIE effect is predominant for tetra-substituted TPE (20.1-fold) than mono-substituted one (4.5-fold).
利用铃木偶联反应合成了三种带有三苯基乙烯部分的新的基于四苯基乙烯的低聚物,并研究了它们的聚集诱导发射特性。它们在常见的有机溶剂中显示出极好的溶解性,并在蓝色区域(440-504 nm)发光。四取代的TPE(20.1倍)的AIE效果比单取代的TPE(4.5倍)更为显着。
