Abstract
The synthesis of asymmetric cyanine dyes (penta- and heptamethines), p repared by coupling Fischer's base with indandione, benzo[b]thiophene and pyrazole derivatives via a C-1 unit, is described. Three different synthetic strategies for substituted polymethines are presented Dye c haracteristics are given and the correlation between the chemical stru ctures and the dye properties are discussed by means of semiempirical PPP calculations.
