项目摘要

The aim of this research project is syntheses of new chelate complexes which have ckiromotropic properties. Chromotropism means the reversible color change due to the changes of chemical or physical environmental conditions such as solvents, temperaure, pressure. electron(redax reaction), light, which is called as Solvatochromism, Thermochromism, Piezochromism, Electrochromism. Photochromism. In this research. We could obtain solvato- and thermo-chromism with Ni(ll) and Cu(ll) mixed ligand (mono- or di-nuclear) complexes in various organic solvents. The key factors for observing such kinds of chromorropisms are (1)the complexes which have an intermediate ligand field strength and (2>he donor and acceptor properties of the solvents used. We used some cyclic diamines, linear ones and the terreamine as the partner ligand and various kinds of beta-diketonates. triketonates and tetraketonate as the another partner, We have Obtained some Fe(Il) and Fe(m) spin-crossover complexes which contain polydentate Schiff-base ligands or tridentate his (imidazole)pyridine, For the electrochromic system, we could try to synthesize Mn(Il and Ill) complexes with a stable polyamino-polycarboxylate ligand, In this case, Mn(II) system is color-less and the Mn(III) analogue is deep red, which is very stable and reversible system. We have to try mixed valence system which show interesting electrochromism in future. We have also obtained many kinds of mixed ligand lanthanide complexes which have the quarternary system, i.e., terpyridine(terpy), acerylacetonate(acac). and nitrate (NO3) : Ln(terpy)(acac)(No3)2.

本研究课题的目的是合成具有变色性能的新型螯合物。向色性是指由于溶剂、温度、压力等化学或物理环境条件的变化而引起的可逆的颜色变化。电子（redax反应）、光，称为溶剂化变色、热变色、压色、电致变色。光致变色。在这项研究中。在不同的有机溶剂中，Ni（II）和Cu（II）的混合配体（单核或双核）配合物都可以获得溶剂化和热致变色。观察这类变色现象的关键因素是：（1）具有中等配位场强度的配合物;（2）所用溶剂的给体和受体性质。我们使用了一些环状二胺、线型二胺和叔胺作为配体和各种β-二酮化合物。以三酮和四酮为另一个配体，合成了一些含多齿或三齿Schiff碱配体的Fe（Ⅱ）和Fe（Ⅲ）自旋交叉配合物对于电致变色体系，我们可以尝试合成Mn在这种情况下，Mn（II）体系是无色的并且Mn（III）类似物是深红色的，这是一个非常稳定和可逆的系统。我们必须尝试混合价体系，显示有趣的电致变色在未来。我们还得到了多种混合配体的镧系配合物，它们具有四元体系，三联吡啶（terpy）、乙酰丙酮（acac）。和硝酸盐（NO3）：Ln（terpy）（acac）（NO3）2。
