Developing highly selective fluorescent probes for the determination of thiophenol is very significant due to its toxicity influence in biological system. In this work, we firstly found that the commercial available cyanine dye 3H-Indolium, 2-(2-(2-chloro-3-(2-(1,3-dihydro-3,3-dimethyl-1-propyl-2H-indol-2-ylidene)ethylidene)-1-cyclohexen-1-yl)ethenyl)-3,3-dimethyl-1-propyl-, iodide had a remarkable...
Four novel imidazole-based dithienylethenes have been successfully synthesized in good yields. Their structures have been confirmed by NMR spectrometry, mass spectrometry, and elemental analyses. UV/Vis absorption spectra indicated that these dithienylethenes can easily isomerize between the open-ring and closed-ring isomers upon irradiation with UV or visible light in solution, and that the respective...
