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).

为了合成具有高导电性和超导电性的新型有机材料，我们的研究小组致力于开发具有与四硫富瓦烯不同骨架的新型电子给体，并评估这些新给体与常见电子受体之间形成的电荷转移（CT）复合物的电学性质，例如，TCNQ。<F_4>这两年的TCNQ和DDQ。本研究中新合成的给体化合物有：乙二叉-2，2 '-双（1，3-二硫杂环戊烯）（1）、乙二叉-2-（1，3-二硫杂环戊烯）-2'-（1，3-二硒烯）（2）、乙二叉-2，2 '-双（1，3-二硒烯）（3）和四（1，3-二硫杂环戊烯-2-亚基）环丁烷的八甲氧羰基-（4a）、未取代的-（4 b）和四苯并-（4c）衍生物。除4a外，其余所有供体均与上述受体形成CT配合物。它们的配合物在压缩颗粒状态下的室温电导率在0.03-0.8 Ω ^（-1）cm^（-1）之间，活化能很小（0.04-0.09 eV）。
