摘　　要：聚集诱导发光(AIE)效应在铀酰离子痕量检测方面具有广阔的应用前景。本文以四苯乙烯(TPE)为母体,设计合成了一种TPE席夫碱类化合物T2,并对其溶液态和聚集态的光学性质进行了表征。结果表明,T2具有AIE特性。并且,当向T2中加入铀酰离子后,体系荧光发射峰从540nm蓝移到500nm,肉眼可见由黄色到黄绿色的明显颜色变化,表明化合物T2可用于检测水体中的铀酰离子。Fluorophores with aggregation-induced emission（AIE） activity has wide application prospects for the detection of trace amount of uranyl ions. In this study,a tetraphenylethylene derivative T2 was synthesized. The optical properties of the solution and aggregation states were characterized,which indicated that T2 shows obvious AIE feature. Moreover,the preliminary studies showed that compound T2 can coordinate with uranyl ion,along with the blue shift of fluorescence emission from 540 nm to 500 nm,and the obvious color change from yellow to yellowgreen. The results indicated that compound T2 has the potential to detect uranyl ion in water.
