The following subjects have been investigated under this research project. 1. Synthesis of new organic donor molecules, 2. Preparation of tha charge transfer complexes of metal-dithiole coordination compounds, 3. Organic conductors with hydrogen bonds, 4. Development of organic anions, 5. Development of C_<60> charge transfer complexes, 6. Development of BEDO-TTF complexes, and 7. Physical and structural study ofBEDT-TTF organic superconductors. More than 40 organic metals including the first metallic Langmuir-Blodgett films based on BEDO-TTF complex have been developed. Four organic superconductors have been developed during this period ; two of them have Tc below 300mK, and the other two have multi-step superconductivity of Tc=8,12,18-23K.The characterizations of the latter two superconductors are under way.

在该研究项目下已经研究了以下主题。 1。新的有机供体分子的合成，2。制备金属 - 二二二二二硫代坐标化合物的电荷转移复合物，3。具有氢键的有机导体，4。有机阴离子的发展，5。c_ <60>电荷转移复合物的发展，6。贝多·TTF复合物的发展。已经开发了40多种有机金属，包括基于Bedo-TTF复合物的第一张金属Langmuir-Blodgett膜。在此期间，已经开发了四个有机超导体。其中两个具有低于300MK的TC，另外两个具有TC = 8,12,18-23K的多步超导性。后两个超导体的特征正在进行中。
