The following subjects have been investigated under this research project : 1. Study of new π-donors bearing the cis-fused aliphatic heterocycles, 2. Study of new π-donors appended with a cyclic acetal, and 3. Study of new π-donors with the periphery extended by alkyl groups. Many molecularbased organic metals have been obtained from these donors, and new donor packing modes conducive to metallic electronic structures have been developed. Furthermore, the development of three new organic superconductors has been achieved by using a non-TTF donor (BDA-TTP). These superconductors are the first examples containing no TTF molecule in an organic donor component, and have been found to have resistive T_c=5.8 -7.5 K.

本研究课题主要研究了以下几个方面：1.含顺式稠合脂肪族杂环的新π-给体的研究，2。新的π-给体附加环缩醛的研究，和3。烷基扩链的新型π-给体的研究。从这些给体中可以得到许多分子基的有机金属，并发展了有利于金属电子结构的新的给体堆积模式。此外，通过使用非TTF供体（BDA-TTP），已经实现了三种新的有机超导体的开发。这些超导体是第一个不含TTF分子的超导体，其电阻T_c=5.8 - 7.5K。
