Abstract

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
