✦ Synopsis

Reflectance spectra ofa single cry&xl of the cbnrge-transfer comples between benzidine and 7,7,8,8-1erracyano-p-quinodimethane (TCNQ) were measured at 30 K. The vibrational structure of the fust charge-transfer band was found to be ISsociated mainly with the intramolecular vibration of TCNQ. From its oscillator strength, the degree of charge transfer was estimated to be 0.28 at room temperature and 0.43 at 30 K. It is concluded that the charge-transfer esciton in this crystal is of ioc&ized nature.

Various extended p-donor molecules incorporating an azino spacer between two heterocyclic moieties, either dithiole or thiazole rings, are described. As evidenced by cyclic voltammetric studies, the donor ability of these derivatives can be modulated depending on the nature of the two heterocycles.
