合成了一种新型二芳烯1-(3,5-二甲基异噁唑-4-基)-2-{2-甲基-5-[(3-亚氨基萘酚-2-基)苯酚基]-噻吩-3-基}全氟环戊烯(1O)双重响应化学传感器,系统地研究了在光和离子刺激下1O的光致变色和荧光开关性质.实验结果表明,1O能够对CN-/F-裸眼识别,在CN-/F-作用下溶液的颜色从无色逐渐变为黄色;同时,1O可作为“Turn-on”型荧光探针对Zn2+进行专一性识别.1O对CN-和Zn2+的检测极限分别达到1.03×10-6和2.98×10-8 mol·L-1.

A new diarylethene 1-(3,5-dimethylisoxazole-4-yl)-2-(2-methyl-5-[(3-aminonaphthol-2-yl)phenol-yl]-thiophene-3-yl)perfluorocyclopentene (1O) dual-response chemosensor has been synthesized, and its photochromic and fluorescent switch behaviors were systematically investigated by stimulation of lights and ions. The results indicated that 1O could serve as a CN-/F- "naked-eyes" colorimetric sensor with the color change from colorless to yellow, and act as a "Turn-on" fluorescence probe for specific detecting Zn2+. Moreover, the limits of detection of CN- and Zn2+ were determined to be 1.03×10-6 and 2.98×10-8 mol•L-1, respectively.
