项目摘要

The purpose of this project is to study properties and function of metal-complex systems under high pressure on the following viewpoints. The high pressure is expected directly and successively to function as a kind of modulation field for the electronic state of metal-complex molecules and systems through the shortening of the distance between the metal and the ligand and between the metal-complex molecules.The following has been performed to study the correlation between the high pressure and the electronic state of metal complexes through the photo absorption using a diamond-anvil-cell and a micro spectrometer.(1) Building up diamond-anvil-cells as a high-pressure apparatus.(2) Construction of a micro-spectrometer system suitable for using the diamond-anvil-cell.(3) Construction of a micro luminescence-spectrometer for ruby chip in diamond-anvil cell to calibrate pressures.(4) Data collection of conditions to generate pressures : culet diameter of diamond-anvil, thickness and hole diameter of gasket, pressure-transmitting medium.(5) a) Synthesis of one-dimensional mixed-valence platinum complexes.b) Photo measurements of the platinum complexes under high pressures.c) Find of modulation of the mixed-valence state with the high pressure.(6) a) Photo measurements of a silver complex with a ligand exhibiting a chromism due to a structure change under high pressures.b) Finding that the silver complex show a pressure-chromism.

本项目的目的是从以下几个方面研究金属络合物体系在高压下的性质和功能。高压有望通过缩短金属与配体之间以及金属配合物分子之间的距离，直接而连续地对金属配合物分子和体系的电子态起到一种调制场的作用，本文利用金刚石压砧光吸收研究了高压与金属配合物电子态的相关性，并对高压与金属配合物电子态的关系进行了讨论。细胞和微型光谱仪。(1)把金刚石砧室建成高压装置。(2)一种适用于金刚石对顶砧的微型光谱仪系统的构建。(3)用于金刚石压腔中红宝石芯片压力标定的微型发光光谱仪的研制。(4)压力产生条件的数据采集：金刚石砧底脚直径、垫片厚度和孔径、传压介质。(5)a）一维混合价铂配合物的合成.B）高压下铂配合物的光测量. c）发现混合价态随高压的调制. (6)a）具有配体的银络合物的光测量，所述配体由于在高压下的结构变化而表现出变色。B）发现所述银络合物表现出压力变色。
