In order to synthesize new organic materials with a high electric conductivity and furthermore superconductivity, our research group had much effort to develop new types of electron donors with a different kind of skeleton from tetrathiafulvalene, and to estimate the electric properties of charge-transfer (CT) complexes formed between these new donors and familiar electron acceptors, e.g., TCNQ. <F_4> TCNQ and DDQ for these two years. The donors newly synthesized in this research are as follows: ethanediylidene-2,2'-bis(1,3-dithiole) (1), ethanediylidene-2-(1,3-dithiole)-2'-(1,3-diselenole) (2), ethanediylidene-2,2'bis(1,3-diselenole) (3), and octacarbomethoxy- (4a), unsubstituted- (4b) and tetrabenzo- (4c) derivatives of tetrakis(1,3-dithiol-2-ylidene)cyclobutane. Except for 4a, all the other donors formed the CT complexes with the above acceptors. The room temperature electric conductivities of their complexes in a compressed pellet state are in the range of 0.03-0.8 <omega^(-1)> <cm^(-1)> , and the activation energies are considerably small (0.04-0.09 eV).

为了合成具有高电导率和超导性的新型有机材料，我们课题组努力开发出与四硫富瓦烯不同骨架的新型电子给体，并评估了电荷转移（CT）的电学性质。 ）在这些新的供体和熟悉的电子受体（例如 TCNQ）之间形成复合物。 <F_4>这两年的TCNQ和DDQ。本研究新合成的供体如下：乙烷二亚基-2,2'-双(1,3-二硫醇)(1)、乙烷二亚基-2-(1,3-二硫醇)-2'-(1,3-二硒醇) (2)、亚乙二亚基-2,2'双(1,3-二硒醇) (3) 和八甲甲氧基- (4a)，未取代的-四(1,3-二硫醇-2-亚基)环丁烷的(4b)和四苯并-(4c)衍生物。除4a外，其他供体均与上述受体形成CT复合物。其复合物在压缩颗粒状态下的室温电导率在0.03-0.8 <omega^(-1)> <cm^(-1)> 范围内，并且活化能相当小(0.04-0.09 eV) ）。
