已经研究了电致变色器件(ECD)的光学和电学性质与电解质浓度和电池间隙的关系。在测试过程中,将电解质浓度从0.01到1 M LiClO 4调节,将正极和负极之间的单元间隙设置为25、60和100 µm。通过改变电解质浓度和电池间隙,可比较分析ECD的透射率,响应时间,电荷消耗,着色效率和双稳性等各种参数。紫精(VO)用作还原电致变色材料,三芳基胺(TAA)用作氧化材料。

In this paper, we reported the synthesis and electroluminescentproperties of blue fluorescent styrylamine derivatives end-capped with a diphenylvinyl group. A new series of styrylamine derivatives have been synthesized via the HornerWadsworth-Emmons reaction. To explore electroluminescentproperties of these molecules, multilayer organic lightemitting devices with the configuration of ITO/NPB/1-5
Carbamodithioate-based compound C1 was designed and synthesized as a new fluorescent probe for Hg2+ ions. Upon the addition of Hg2+ ions, it displayed a rare staged response: the emission spectra of C1 first showed an apparent red-shift, followed by a dramatic decrease. To investigate the sensing mechanism, control compounds C2 with the same phenanthroimidazole unit and C3 with the same carbamodithioate functionality were synthesized. On comparison, the first step sensing process was ascribed to decreasing photoinduced electron transfer on the coordination of Hg2+ with the lone pair electrons of the nitrogen atom on the phenanthroimidazole ring. The affinity of Hg2+ and the carbamodithioate unit with four sulfur atoms then induced changes in intramolecular charge transfer efficiency and the second step fluorescent response.
