The reaction of N,N-bis(2-hydroxyethyl)aniline 1 with tetracyano-p- quinodimethane (TCNQ) 2 yields the photochromic red chromophore 3 [λ(max) (acetone/dichloromethane) 497 nm] which upon UV irradiation is converted into the blue zwitterionic form 3' (λ(max) 680 nm) by a novel intramolecular charge transfer process involving a D-quinoid-aryl-A→D+-aryl-quinoid-A- conversion. The analogous process occurs in the polyimide derived system 8. Different products are isolated from reactions of 1 with the stronger electron acceptors TCNQBr2 and TCNQF4.
