聚集诱导发光酸碱刺激响应荧光传感材料

Aggregation Induced Luminescent Acid-base Stimulus Responsive Materials

酸碱刺激响应发光材料是一类在外界pH值的刺激作用下,荧光发射光谱可以做出变化的材料,在荧光探针、光电器件和生物传感等领域有潜在的应用价值,但是传统的酸碱刺激响应材料存在ACQ问题,限制了该类材料在聚集状态下的应用,而AIE材料能够解决ACQ问题,近十几年来发展迅速。本文分别从常见酸碱刺激响应的四种结构类型:席夫碱型、吡啶盐类、吲哚类和噻唑类进行分类介绍,对其结构-性能关系进行阐述,展望AIE酸碱刺激响应发光材料的发展方向。

Acid/alkali responsive luminescent materials are a kind of materials whose emission spectra can be changed under the stimulation of external pH value,which has potential application value in the fields of fluorescent probes,optoelectronic devices and biosensors.However,the ACQ problem of traditional acid responsive materials limits the application of such materials in the aggregation state,while AIE materials can solve the ACQ problem.It has developed rapidly in the past ten years.In this paper,four common types of acid responsive structures,Schiff bases,pyridines,indoles and thiazoles,were classified and introduced.The relationship between the structure and properties of AIE was described.The development direction of AIE acid responsive luminescent materials was prospected.
