The symmetric cyanine dyes 2a - c, 3a, 4a, and 5a were transformed into the leuko compounds 7 - 10, 12, and 14.Deprotonation of 7 and 8 with lithium diisopropylamide led to the corresponding cyanine dye anions, which yielded derivatives of the leuko compounds (25 - 30 and 34, 35, respectively) with electrophiles.The cyanine dyes 2a, 3a and the leuko compounds 7, 8 delivered with lithium tetracyano-p-quinodimethan anion (LiTCNQ) and tetracyano-p-quinodimethan (TCNQ) simple (36, 37) and complex salts (38, 39), respectively. 39 displayed interesting conductivity.
