摘要： 用碘甲烷及碘乙烷与2,5,6-三甲基苯碲唑、2-甲基。5-羟基苯并碲唑反应,合成了4种苯并碲唑碘化季铵盐。进一步与原甲酸乙酯反应制得了相应的新型碲碳菁染料。测定了它们在不同溶剂中的可见吸收光谱,讨论了取代基及溶剂对最大吸收波长的影响。

关键词: 苯并碲唑, 菁染料, 碲碳菁染料, 光谱增感剂, 合成

Abstract: Four noveI telluracarbocyanine dyes have been synthesized from quaternary ammonium iodides of benzotellurazole with ethyl orthoformate. The former was synthesized by treatment of 2,5,6.trimt1i1、yl benzotellurazole and 2-methyl-5-hydroxylbenzotellurazole with methyl or ethyl iodide,respectively. The visible absorption spectra of the dyes in different solvents were recorded. The effects of the solvents and substituents on the spectra of the dyes are discussed.

Key words: benzotellurazole, cyanine dye, telluracarbocyanine dye, spectral sensitizer, synthesis
