The effects of acid on the absorption spectra, fluorescence spectra and thermal stability of L are investigated. The results show that the acid effect on the absorption spectra of L is very little, but the fluorescence spectra and thermal stability of L can be effectively regulated by the acid. In addition, L shows good photochromism before and after the protonation, as well as the distinctive "on to on" fluorescence characteristic., authors=PENG Xuefeng1, HOU Jieping1, YU Haibin1, ZHANG Jingcheng1, XU Haibing2, authorsList=PENG Xuefeng, HOU Jieping, YU Haibin, ZHANG Jingcheng, XU Haibing, authorCompany=1.

设计合成了4,5-双(5-氯-2-甲基噻吩-3-基)-1,2-二苯基-1H-咪唑化合物L,通过1HNMR、13CNMR 和元素分析对其分子结构进行表征,并研究了酸效应对其吸收光谱、荧光光谱和热稳定性的影响。结果表明,酸效应对化合物L 吸收光谱的影响很小,但通过酸效应能够对化合物L 的荧光光谱和热稳定性进行有效的调节。另外,化合物L 在质子化前后均表现出良好的光致变色性能,并显示出与众不同的“on to on”荧光特性。

4, 5-bis(5-chloro-2-methylthiophen-3-yl)-1, 2-diphenyl-1H-imidazole (L) is synthesized and characterized by 1H NMR, 13C NMR and elemental analysis. The effects of acid on the absorption spectra, fluorescence spectra and thermal stability of L are investigated. The results show that the acid effect on the absorption spectra of L is very little, but the fluorescence spectra and thermal stability of L can be effectively regulated by the acid. In addition, L shows good photochromism before and after the protonation, as well as the distinctive "on to on" fluorescence characteristic.
