We are reporting two general synthetic approaches to a number of (aminostyryl)pyridinium dyes and their heterocyclic analogues which are of interest as electrochromic probes for membrane potential. The two routes which involve palladium-catalyzed coupling or aldol condensation permit considerable structure variations to be introduced in the dyes. Some spectral properties of the dyes are discussed.
