been widely used as chromophore in design of fluorescent probe, while less coumarin‐based fluorescent probe was reported for detection of anion in water. In this article, coumarin‐based fluorescent probes with salicylaldehyde functionality as recognition unit have been developed for selective detection of bisulfite anions in water. Four novel fluorescent probes were synthesized from 4‐haloresorcinol in
香豆素及其类似物已被广泛用作荧光探针的设计中的生色团,而据报道,基于香豆素的荧光探针可用于检测水中的阴离子。在本文中,开发了以水杨醛功能为识别单元的基于香豆素的荧光探针,用于选择性检测水中的亚硫酸氢根阴离子。由四个卤代间苯二酚分三步合成了四种新颖的荧光探针。化学探针对亚硫酸氢盐的选择性反应优于其他阴离子。此外,还研究了检测机制。加入亚硫酸氢盐后,由于甲酰基与亚硫酸氢盐阴离子的亲核加成反应,探针的荧光强度大大提高。
