Polymethine dyes containing a bridging group in the polymethine chain and substituents of various electronic types were obtained by the condensation of the salts of the dianils of substituted glutaconaldehyde with malonitrile in an alkaline medium.The spectral characteristics of the synthesized dyes were investigated.
