We introduced supramolecular cations composed of inorganic cations and crown ethers into [Ni(dmit)2 crystals and developed novel molecular systems in which electronic condction and ionic conduction coexisted.We also regulated [Ni(dmit)_2]^- assemblies in the crystal utilizing supramolecular cation structures and revealed that we could control magnetic and electronic properties through the molecular-assembly control.To develop nanometer-size materials and devices from molecular charge transfer complexes, we investigated the formation of molecular films of charge transfer complexes. Especially, we used Langmuir-Blodgett method and succeeded in forming single-component conducting films. In addition, we studied self-assembly monolayers in which TTF skeleton directly attached to gold surface. We found that when we apply the Langmuir-Blodgett method to macrocyclic TTF molecule that has ion-recognition ability, the molecules forms nanowire structures. Moreover, when we used mica substrates, the nanowires recognized ionic array of the surface and oriented specific directions. These results strongly indicate that the molecular charge transfer complexes are quite useful to developing future molecular electronic devices.

我们将由无机阳离子和冠醚组成的超分子阳离子引入到[Ni(dmit)2晶体中，开发了电子传导和离子传导共存的新型分子体系。我们还利用超分子阳离子结构调控了晶体中的[Ni(dmit)_2]^-组装体，揭示了通过分子组装体可以控制磁性和电子性质。 为了利用分子电荷转移复合物开发纳米尺寸材料和器件，我们研究了电荷转移复合物分子膜的形成。特别是，我们使用Langmuir-Blodgett方法成功地形成了单组分导电薄膜。此外，我们还研究了TTF骨架直接附着在金表面的自组装单分子层。我们发现，当我们将Langmuir-Blodgett方法应用于具有离子识别能力的大环TTF分子时，分子形成纳米线结构。此外，当我们使用云母基底时，纳米线识别表面的离子阵列并定向特定方向。这些结果强烈表明分子电荷转移复合物对于开发未来的分子电子器件非常有用。
