    Selective photoconversion of photochromic diarylethenes and their properties
    摘要:
    选择性光转化的光致变色日苯基乙烯衍生物已通过日苯基乙烯衍生物1a作为模型化合物进行了描述。经254 nm光照射,1a在无氧条件下发生光环化,生成环闭异构体1b;在有氧(空气)条件下则转变为硫内酯衍生物1c。研究发现,1b可以通过可见光照射逆转回1a,且在无氧条件下可以进行开环和闭环的光开关操作。然而,1c是光惰性,无法通过紫外光或可见光照射逆转回1a。此外,发现1c具有荧光,而1a和1b均不显示荧光。

    Synthesis and photophysical properties of thiolactone derivatives
    摘要:
    A class of bis-thiolactone derivatives is prepared by photo-conversion of photochromic diarylethenes with a bis (5-chloro-2-methylthiophen-3-yl) system in moderate yields (50-60%). Bis-thiolactone derivatives show fluorescence in solution with moderate fluorescent quantum yields (0.11-0.17). Reaction mechanism exhibits that the photo-conversion of diarylethenes to bis-thiolactone derivatives undergoes a two-step reaction: photocyclization and photo-oxidation. (C) 2013 Elsevier Ltd.

  • Imidazole-Based Dithienylethenes: Synthesis, Photochromism, and Effects of Metal Ions
    作者:C. Zhang、Z. Chen、C. Jiang、Guang-Ao Yu、S. H. Liu、J. Yin

    日期:2013.6.1
    A series of imidazole-bridging dithienylethenes was synthesized by the condensation of thiophene-based diketone and methoxyl-substituted benzaldehyde. Their UVVis absorption and fluorescent spectra were investigated before and after irradiation with UV light. It is worth mentioning that the metal ions such as Cd2+, Cu2+, Fe3+ can obviously enhance the intensity of emission spectra.
