Six novel disubstituted phenylene‐linked bis‐imidazole derivatives, 3a–3f, were prepared by a one‐pot, microwave‐assisted method under solvent‐free conditions, in yields ranging from 61.6 to 85.6%. The new compounds were characterized by 1H‐ and 13C‐NMR, UV/VIS, and fluorescence spectroscopy, and mass spectrometry, as well as by elemental analyses. The influence of substituents and solvents on the
在无溶剂条件下,通过单锅微波辅助法制备了六种新颖的二取代亚苯基联苯二咪唑衍生物3a - 3f,产率为61.6%至85.6%。这些新化合物的特征在于1 H-和13 C-NMR,UV / VIS,荧光光谱,质谱以及元素分析。研究了取代基和溶剂对3a - 3f光学性能的影响。已经发现,与发射光谱相反,对吸收光谱和激发光谱的影响很小。化合物3a – 3f 在溶液中显示出强荧光,其荧光量子产率为0.27至0.96。
