Development of purely organic single-component conductors

合成了几种由DT-TTF和二氰甲基、二氰喹诺二甲烷基团组成的新型给受体（D-A）体系衍生物1-5。循环伏安法表明，化合物1和3表现为多阶段氧化和一次还原过程。1和3的红外光谱显示了相当大的极化结构贡献。电子能谱和理论计算（DFT方法）表明，在900 nm附近的吸收最大值为1是由于分子内电荷转移引起的。D-A系统1在单晶上的电导率为10e - 5s /cm，尽管是单组分材料。

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.
