Four intermediates and six merocyanine dyes containing benzotellurazoles were described. The synthetic conditions were dependent on different acidities of ketomethylene nuclei. The solvent effects on absorption spectra of the dyes were investigated and the different solvent effects for different types of merocyanines were explained by resonance theory. The characteristics of the above dyes as solvent polarity indicator were also evaluated.

Key words: CYANINE DYES, MEROCYANINE, DYE INTERMEDIATE, HETEROCYCLIC COMPOUNDS
