Development of purely organic single-component conductors

Several derivatives of brand-new donor-acceptor (D-A) systems 1-5 composed of DT-TTF and dicyanomethylidene and dicyanoquinodimethane groups were synthesized. Cyclic voltammetry revealed that the compound 1 and 3 exhibited multi-stage of oxidation and one-stage of reduction processes. The IR spectra of 1 and 3 demonstrated considerable contribution of polarized structures. Electronic spectra and theoretical calculation (DFT method) suggested that the absorption maximum of 1 at around 900 nm was due to intramolecular charge-transfer. The D-A system 1 exhibited conductivity of 10E-5 S/cm on a single crystal in spite of a single-component material.
