Design and Development of the Transition Metal Complexes Having Multi Functional Properties.

介于有机材料和无机材料之间的过渡金属配合物具有多种多功能性质，并具有光学、磁性或输运性质。为了寻找和开发新的多功能性质的过渡金属配合物，我们组织了题为“具有多功能性质的过渡金属配合物的设计与开发”的科研资助项目。在项目期间（1995-1996），我们项目的显著成果如下：(1) (BETS) _2FeCl_4中由d-pi相互作用驱动的场诱导绝缘体到金属的转变，(2)(BETS) _2Ga_<1- x >Fe_XCl_4中超导相和反铁磁相的竞争，(3)[Pd (H_2DAG) (HDAG)]TCNQ （M=Ni, Pd, Pt）中由d-pi电子转移和质子转移耦合驱动的奇异金属-绝缘体转变，(4)新铁磁体和铁磁体的发展，(5)新自旋交叉配合物的发展，(6)混合价MX链体系中存在密集的非线性激发，如孤子或极化子；(7)混合价MX链体系中金属-绝缘体跃迁；(8)过渡金属团簇配合物的高度非线性光学（SHG）的发展；(9)配位聚合物的光诱导配体驱动晶体振动。

Transition metal complexes which are located between organic and inorganic materials hava a possibility of various kinds of multi-functional properties mixed with optical, magnetic or transport properties. In order to search and develop new multifunctional properties for transition metal complexes, we have organized the research project, grant-in-aid for scientific research whose title is "Design and Development of the Transition Metal Complexes Having Multi-Functional Properties".During the term of the project (1995-1996), the noticeable results of our project are following ; (1) Field induced insulator-to-metal transition in (BETS) _2FeCl_4, which is driven by the d-pi interaction, (2) Competition between the superconducting and antiferromagnetic phases in (BETS) _2Ga_<1-X>Fe_XCl_4, (3) An exotic metal-insulator transition driven by the d-pi electron transfer coupled with proton transfer in [Pd (H_2DAG) (HDAG)]TCNQ (M=Ni, Pd, Pt), (4) Development of new ferromagnets and ferrimagnets, (5) Development of new spin crossover complexes, (6) Existence of dense nonlinear excitations such as solitons or polarons for mixed-valence MX chain system, (7) Metal-insulator transition in mixed-valence MMX-chain system, (8) Development of highly nonlinear optics (SHG) for transition metal cluster complexes, (9) Photo-induced ligand-driven crystalline vibration for coordination polymer.
