Notes: Synthesis and Properties of Trimethinecyanines with Bridged ChainsThe effects of meso-substituents (H, morpholino, ethoxy) and hydrocarbon bridges, on the light absorption and the electrochemical properties of trimethinecyanine dyes (4a--f, 8a-c 10a-f) are investigated. The results are in a good agreement with the predictions of the perturbation theory. Methods for the preparation of the dyes involving reaction of methylthio quaternary salts (1a, b) with enamines (2a, b) are described.
