Research progress in mechanochromic luminescent complex materials
As an intelligent light-responsive material,mechanochromic luminescent materials can respond to external stimuli and exhibit a reversible transformation of photophysical signals.This kind of material has the advantages of simple operation,sensitive response,easy observation,and reusability.It is widely used in many fields,such as optical switches,security and confidentiality,data recording,and security and anti-counterfeiting.The complex material introduces metal ions into the assembly process of organic molecules,which effectively improves the photothermal stability,and coordinates to enrich the intermolecular packing mode,providing a breakthrough for the design of new mechanoluminescent color-changing materials.This review summarizes the research progress in luminescent color-changing complex materials in the past five years,comprehensively analyzes the construction strategies,performance research methods,and potential application value of such materials,and proposes further problems to be solved from two aspects:mechanism research and practical application,in order to achieve industrial mass production and practical application as soon as possible.
