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 1 H NMR spectral data. The spectral behaviour of all the synthesized cyanines was examined in 95% ethanol.
