摘要 光致变色材料由于其独特的光响应行为以及作为智能材料的应用前景而引起了人们的极大关注。合成了兼具四苯基乙烯、氰基二苯乙烯2种聚集诱导发光(AIE)基元的荧光分子TPE-4DCS,并对其光物理性能进行了系统研究。光谱实验结果表明,TPE-4DCS具有典型的AIE性质。并且,由于氰基二苯乙烯单元的可逆Z/E异构化,TPE-4DCS溶液的荧光强度在365 nm紫外光照射下会逐渐减弱并出现光谱蓝移,而在254 nm紫外光照射下荧光又可以恢复。因此,TPE-4DCS是一种新型的光响应材料,在荧光传感等领域具有潜在应用价值。

Abstract: Photochromic materials have attracted great attention due to their unique photoresponsive behavior and prospective applications as intelligent materials. In this work, a fluorescent molecule TPE-4DCS with two aggregation-induced emission (AIE) groups, tetraphenylethylene and cyanostilbene, was synthesized and its photophysical properties were systematically investigated. The results of the spectra experiments showed that TPE-4DCS has the typical AIE properties. Moreover, due to the reversible Z/E isomerization of the cyanostilbene unit, the fluorescence intensity of the TPE-4DCS solution gradually decreases under 365 nm UV irradiation and shows a spectral blue shift, while the fluorescence can be recovered under 254 nm UV irradiation. Therefore, TPE-4DCS is a new material with potential application in fluorescence sensing and other fields.
