Abstract

Abstract New unsymmetrical 2[2(4)]‐mono‐and tri (substituted tri)‐methine cyanine dyes incorporating 1,2,5,6‐tetrahydro‐4,6‐diaryl pyrimidine (pyrimidinium‐1‐yl salt)‐2‐one were prepared. Structural determination was carried out by elemental analysis, IR and 1H NMR spectral data. The spectral behaviour of all the synthesized cyanines was examined in 95% ethanol.
