摘要： 多甲川染料已广泛用于银盐感光材料、电子照相、染料激光器、光记录介质及太阳能转换体系等方面。其中苯乙烯多甲川染料具有宽的吸收光谱,引起人们的重视。我们曾合成了含吡喃鎓多甲川染料,它们与含氮杂环的多甲川染料相比,吸收波长红移,并具有极好的光化学稳定性。本文合成了含吡喃鎓端基的二甲川及四甲川苯乙烯染料,测定了电子吸收光谱。

关键词: 苯乙烯染料, 合成, 吡喃鎓; 电子吸收光谱

Abstract: The synthesis of some new styryl dyes containing pyrylium end group is described. The structure of the compound was confirmed by elemental analysis, IR spectra and 1H NMR spectroscopy.The electronic absorption spectra of the dyes in red and near infrared region is reported.

Key words: styryl dye, synthesis, pyrylium, electronic absorption spectrum
