Three BODIPY-based ratiometric fluorescent probes (1, 2 and 3), with two being highly soluble in aqueous solution, were prepared by the condensation of 2-formyl-BODIPY dyes with 2,3,3-trimethyl-1-propyl-3H-indolium iodide and 2,3,3-trimethyl-1-(3-sulfonatepropyl)-3H-indolium for the selective and sensitive ratiometric fluorescent responses to cyanide ions.
三种基于BODIPY的比率荧光探针(1、2和3)已经制备,其中两个在
水溶液中具有高溶解度,通过2-醛基-BODIPY
染料与2,3,3-三甲基-1-丙基-
3H-吲哚唑
碘化物和2,3,3-三甲基-1-(3-
磺酸丙基)-
3H-吲哚唑的缩合反应,针对
氰离子进行了选择性和敏感的比率荧光响应。
