Abstract: Five asymmetric crown telluracarbocyanines were prepared. The visible absorption spectra and the “Brooker diviation” of four of them have been studied. The method of reduction and acylation of 4-nicrobenzo-15-crown-5-has been improved, making the synthesis of the asymmetric crown ether telluracarbocyanine dyes quite convenient and easy.

Key words: crown ether telluracarbocyanine, synthesis, absorption spectrum
