Abstract
A series of acridinium salt-based probes capable of detecting fluoride and acetate anions via a nucleophilic attack at the C9 position of the acridinium moiety is reported. The formation of corresponding acridane displays drastic changes, in both UV-vis absorption and fluorescence emission. The sensing mechanism is a reversible process upon treating either tetrafluoroborate salt or an acid.
摘要
报道了一系列基于吖啶鎓盐的探针，其能够通过对吖啶鎓部分C9位的亲核进攻来检测氟离子和醋酸根阴离子。相应吖啶烷的形成在紫外可见吸收和荧光发射方面都显示出显著变化。传感机制在处理四氟硼酸盐或酸时是一个可逆过程。
