合成了一种新型的带有两个8-羟基喹啉基团的四硫富瓦烯衍生物3，通过光学和电化学变化对Zn 2+进行选择性检测。Zn ~（2+）和Cd ~（2+）的加入引起了荧光强度的显著变化，这是由于羟基喹啉和1，2，3-三唑环的螯合增强荧光效应。3在Zn 2+存在下的电化学电位相对于测试的其他金属阳离子的电化学电位向更正值移动。
A novel clicked tetrathiafulvalene derivative 3 bearing two 8-oxyquinoline groups was synthesized for the selective detection of Zn2+ through optical and electrochemical changes. The addition of Zn2+ and Cd2+ induced a significant change in fluorescence intensity, which was attributable to the chelation-enhanced fluorescence effect from the oxyquinoline and 1,2,3-triazole rings. The electrochemical potentials of 3 in the presence of the Zn2+ were shifted toward more positive values relative to those of the other metal cations tested.
