具有压力响应的环三核金属配合物的设计合成及发光性质研究

平面型金属配合物在压致发光变色材料应用方面具有极大的研究价值和潜力。本项目拟以吡唑环三核Cu(I)、Ag(I)、Au(I)单元作为结构基元，通过设计和选择链状连接单元，结合多种具有平面结构的发光有机基团，设计制备具有压力响应的环三核金属配合物材料。调整金属离子、配体以及取代基的电子效应、空间效应及超分子作用，实现此类材料的分子结构、空间堆积及发光性质的有效调控。利用先进的高压光谱技术，借助理论化学计算，探索此类材料的压致发光变色现象，并从微观尺度揭示其刺激响应机理，建立结构与压致变色性能间的构效关系，最终为拓展金属环三核配合物在刺激响应智能材料上的应用提供实验及理论也依据。

Metal complexes with planar structures, are of great research value and potential in piezoluminescent materials. This project focus on designing and synthesizing a series of pressure stimuli responsive materials by using trinuclear cyclic Cu(I), Ag(I), Au(I) coordination units as essential building blocks, combining various light-emitting organic groups throughout conjugated/non-conjugated linkers. The molecular structure, intermolecular stacking and luminescent properties of these complexes will be controlled by the electronic effects, steric effects and supramolecular effects of metal ions, ligands, and substituents, effectively. This project aims to explore the piezoluminescence phenomenon and reveal the stimuli response mechanism from the microscopic scale by means of advanced high-pressure spectroscopy technology and theoretical chemical calculations, and then establish the intrinsic relationship between the structure and the piezochromic properties. We expect to expand the applications of trinuclear cyclic complex on stimuli responsive materials and smart materials.
