摘　　要：材料在压力作用下可出现不同的响应行为,如硬化、压缩性、光学性质改变等,依此设计出具有优异力学、机械以及发光性能的材料,是设计新型功能材料的重要途径。本文将介绍课题组近年来在新型压致响应功能晶体材料研究中取得的进展,基于碳及碳骨架分子,设计不同的碳基分子共晶,利用高压技术,设计构筑出系列具有潜在超硬特性、负体积压缩性的材料以及反常压力响应的发光材料。Materials that exhibit obvious pressure responses upon compression,such as hardening,compressibility and optical properties change,and so on,which have been explored as an important way to design new functional materials with desired mechanical properties and luminescent properties.Here,we will introduce some recent progress on the research of new pressure responsive functional crystalline materials with novel properties.A new strategy has been developed to design and construct new functional materials by application of high pressure to the designed co-crystals.The co-crystals have been designed based on carbon and carbon-based molecules and studied by high pressure technique.A series of new materials with potentially superhard properties,negative volume compressibility and anomalous pressure response in luminescence has been obtained.
