Development of Novel Organic Conductive Materials

在这个项目中，我们设计了新型的电子供体和受体，以开发导电的电荷转移配合物。因此，合成了各种电子给体，如环硫桥芳烃、萘熔接TTF类似物和多缩合噻吩，其中大多数作为中等电子给体并形成半导体。另一方面，对噻吩- tcnq、硒代- tcnq、呋喃- tcnq、吡啶- tcnq等杂基tcnq的受体类型进行了研究。其中，共轭噻吩-或硒代噻吩- tnoq由于减少了现场库仑排斥而成为较好的电子受体，因此它们与各种给体形成了高导电性的分子配合物。

In this project, we have designed new types of electron donors and acceptors in order to develop electrically conductive charge-transfer complexes. Thus various electron donors such as peri-chalcogen-briged arenes, naphthalene-fused TTF analogues, and multi-condensed thiophenes were synthesized, most of which acted as moderate electron donors and formed semi-conductors. On the other hand, hetero TCNQs such as thiophene-TCNQ, selenophene-TCNQ, furan-TCNQ, and pyridine-tcno were studied for acceptor type. Of them, conjugated thiophene- or selenophene-TCNOQ were found to be superior electron acceptors owing to diminution of on-site Coulomb repulsion, and accordingly they formed highly conductive molecular complexes with a variety of donors.
