本研究项目旨在通过设计和合成具有电子离域特征模式的新型共轭分子和分子体系来创造具有特征功能和物理性质的有机材料。特别是，通过构造动态的电子离域系统来寻找前所未有的复杂函数，这种系统可以通过施加热、光、磁场、电场等来交换函数。主要研究成果如下：(AO1)。扩展共轭体系群集中于新型扩展共轭分子和超分子的合成与开发，具有新的拓扑结构和新的功能。(AO2)自旋共轭电子体系群探索和表征了各种稳定的开壳物种，包括可饱和的卡宾、过硅基苯二阴离子、硅和铅的二价物种以及具有合理稳定性和高自旋态的手性有机磁体。(A03)质子-电子耦合体系群通过创新概念、构建新的分子体系和控制分子的电子功能，探索了质子-电子合作体系、质子动态介电响应体系和电子-氢电荷转移体系。

This research project aims to create organic materials which show characteristic functions and physical properties, by designing and synthesizing novel conjugated, molecules and molecular systems having characteristic mode of electronic delocalization. Especially, unprecedented and complex functions are searched by constructing dynamic electronic delocalized systems which can interchange functions by applying heat, light, magnetic field, eletric field, and so on. The main research results are as follows :(AO1) The. Group of "Extended conjugated systems" have intensively carried the synthesis and development of novel extended conjugated molecules and supramolecules with new topologies and new functions.(AO2) The group of "Spin conjugated electronic systems" has explored and characterized various stable open-shell species which include satiable carbene, persilylbenzen dianion, divalent species of Si and Pb, and chiral organic magnets with reasonable stability and high spin states.(AO3) The group of "Proton-electron coupling systems" has explored the proton-electron cooperative systems, proton dynamic dielectric response systems, and electron-hydrogen-charge transfer systems by creating new concept, constructing new molecular systems and controlling molecular electronic functions.
