[摘要]：Several derivatives of a new donor-acceptor diad 1 composed of DT-TTF and dicyanomethylidene group were synthesized. The IR spectra of 1 demonstrated considerable contribution of a polarized structure. Electronic spectra and molecular orbital calculation suggested that the absorption maximum of 1 was due to NHOMO-LUMO transition. Cyclic voltammetry revealed that the compound 1 exhibited three-stage of oxidation and one-stage of reduction processes. The bis(methylthio)-substitudted derivative 1a exhibited conductivity of 10(-6) S cm(-1) in spite of a single-component material. |
