具有聚集诱导发光性质的力致荧光变色材料的研究进展

Research Progress of Mechanofluorochromic Materials with Aggregation Induced Emission

力致荧光变色(mechanofluorochromic,MFC)是指材料在外部机械力作用下(如研磨、挤压等)发生自身物理和化学性质变化引起发光发射波长和强度等光物理性质的改变,并且其一般可在加热、有机蒸汽熏蒸的条件下恢复到初始状态。外界压力响应变化这一特性,使得力致荧光变色材料在信息传感、数据储存等方面具有广阔的应用前景。力致荧光变色材料种类多样,本文主要针对具有聚集诱导发光(aggregation induced emission,AIE)特性的几种不同类别的力致荧光变色材料进行总结阐述。

Mechanofluorochromic(MFC)material refers to the change of its own physical and chemical properties under the action of external mechanical force(such as grinding,extrusion,etc.),which causes the change of photophysical properties such as emission wavelength and intensity,and can generally return to the initial state upon heating and organic vapour.Due to the unique properties,MFC materials have broad application prospects in information sensing,data storage and so on.There are many kinds of mechanochromic materials.This paper maily focuses on several different types of mechanochromic materials with aggregation induced emission(AIE)characteristics.
