近年来，力致发光变色材料因其具有操作简单、对环境友好等优点，在存储、压力传感和加密防伪等领域受到越来越多的关注。AIE材料报道之前，力致发光变色化合物的数目十分有限，并且化合物的合成与性质基本没有规律。在AIE报道之后，人们发现许多AIE化合物都具有力致发光变色性质。这一发现所建立的结构与性质之间的关系，对合成更多的新型力致发光变色材料大有帮助。

本论文概述了力致发光变色材料的研究进展，分别介绍了无AIE现象的力致发光变色材料和有AIE现象的力致发光变色材料，并对力致发光变色的机理进行了较为详细的阐述。本实验基于AIE原理，以邻苯二胺，2-氨基-4-溴苯甲酸为原料，以多聚磷酸为溶剂，设计合成了具有多个芳香环的配体L¹。之后以L¹和水杨醛为原料，设计合成了具有多个芳香环的配体L²。此外，本实验以2,3-二氨基顺丁烯二腈，二苯氨基-4-苯甲醛为原料，采用溶剂热合成法设计合成了具有多个芳香环的AIE配体L³，并初步探索了配体L³的光物理性质及AIE性质，初步阐释了AIE化合物与力致发光变色性质之间的关系。

In recent years, materials with mechanochromic luminescence have attracted more and more attention in the fields of storage, pressure sensing and encryption and anti-counterfeiting because of their advantages of simple operation and environmental friendliness. Before AIE materials were reported, the number of materials with mechanochromic luminescence was very limited, and the syntheses and properties of compounds were basically irregular. After AIE was reported, it was found that many AIE compounds have mechanochromic luminescence properties. The relationship between structure and properties established by this discovery is very helpful for the synthesis of more new materials with mechanochromic luminescence .
This paper summarizes the research progress of mechanochromic luminescence materials, introduces the mechanochromic luminescence materials without AIE phenomenon and the mechanochromic luminescence materials with AIE phenomenon, and expounds the mechanism of mechanochromic luminescence in detail. Based on the principle of AIE, ligand L1 with multiple aromatic rings was designed and synthesized with o-phenylenediamine and 2-amino-4-bromobenzoic acid as raw materials and polyphosphate as solvent. Then, ligand L2 with multiple aromatic rings was designed and synthesized from L1 and salicylaldehyde. In addition, AIE ligand L3 with multiple aromatic rings was designed and synthesized by solvothermal synthesis with 2,3-diaminomaleic dinitrile and diphenylamino-4-benzaldehyde as raw materials. The photophysical properties and AIE properties of ligand L3 were preliminarily explored, and the relationship between AIE compounds and mechanochromic luminescence properties was preliminarily explained.
