主 题：Fluorescent chemosensor Cyanine Silver ion detection Industrial wastewater
摘 要：An efficient fluorescent probe 1 based on tricarbocyanine derivative was designed and synthesized,which can detect Ag^(+) in real industrial ***-V is absorption and fluorescent emission spectra of probe 1 were carried out and indicated this probe can bind Ag^(+) via complexation reaction,then leading to a remarkable color change from blue to light ***,probe 1 showed high sensitive performance and excellent selectivity toward Ag^(+) over other common metal ions in neutral *** sensing mechanism was proposed and further confirmed by ^(1)H NMR,which demonstrate analyte-induced destruction of the π-electron system could be shorten by the disruption of the pull-push π-conjugation system in probe ***,a test strip was prepared by filter paper immersing in probe 1 solution,which further provide its potential application for trace Ag^(+) detection in real industrial wastewater.
