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。Four noveI telluracarbocyanine dyes have been synthesized from quaternary am-monium iodides of benzotellurazole with ethyl orthoformate. The former was synthesized bytreatment of 2,5,6.trimt1i1、yl benzotellurazole and 2-methyl-5-hydroxylbenzotellurazole withmethyl or ethyl iodide,respectively. The visible absorption spectra of the dyes in differentsolvents were recorded. The effects of the solvents and substituents on the spectra of thedves are discussed.
