摘要
聚集诱导发光(Aggregation-Induced Emission,AIE)荧光材料因其独特的光学特性,在信息存储、智能传感及生物技术等众多领域展现出了广阔的应用前景。针对AIE发光稳定性差及缺乏刺激响应能力等问题,利用无溶剂研磨法将四(4-吡啶基苯基)乙烯与Y型沸石进行杂化复合制备了具有AIE性质的TPE-Py@ZY复合物。结果表明:该复合物比四(4-吡啶基苯基)乙烯具有更好的热稳定性,并且通过pH值刺激可以实现荧光颜色从亮青色到黄色的转变。这种具有荧光颜色刺激响应的AIE材料对于推动智能荧光材料的实际应用具有重要的意义。
AIE fluorescent materials have shown broad application prospects in many fields such as information storage,smart sensing and biotechnology due to their unique optical properties.However,AIE luminogens still face problems such as poor stability and lack of stimulus responsiveness.Tetra-(4-pyridylphenyl)ethylene and zeolite Y were compounded by solvent-free grinding to prepare TPE-Py@ZY composite with aggregation-induced emission.The composite has better thermal stability than tetra-(4-pyridylphenyl)ethylene,and the fluorescence color can be transformed from bright cyan to yellow by pH stimulation.This AIE composite with fluorescence color stimulus response is of great significance for promoting the practical application of smart fluorescent materials.
