Abstract

A novel and efficient thiosemicarbazone based chemosensor for the detection of transition metals through UV-visible fluorescence has been reported in this research. Dibenzyl thiosemicarbazones can bind with the transition metal ions and lead to the enhancement of the fluorescence. The reported dibenzyl thiosemicarbazone can detect Zn2+, Co2+, Ni2+ and Hg2+ appreciably due to inhibition of electron transfer while quenching of fluorescence occurs in Mn2+ and Cu2+ due to photoinduced electron transfer.

基于硫代氨基羰基化合物的新型过渡金属传感器†
本研究报告了一种基于硫代氨基脲的新型高效化学传感器,可通过紫外可见荧光检测过渡金属。二苄基硫代氨基甲酸唑能与过渡金属离子结合,从而增强荧光。所报告的二苄基硫代氨基甲酸唑能明显探测到 Zn2+、Co2+、Ni2+ 和 Hg2+,这是由于电子传递受到抑制,而 Mn2+ 和 Cu2+ 则由于光诱导电子传递而发生荧光淬灭。
