合成了一种基于4-N,N-二甲氨基苯基水杨醛的席夫碱。它具有独特的溶液-固体双发射行为,具有发射颜色:液体中聚集诱导的明亮绿松石发射和固体中强烈的近红外发射。有趣的是,一方面,化合物1有望成为一种检测水溶液中锌离子的比率荧光探针,具有高灵敏度、高选择性和相对低的检测下限。另一方面,基于其内在的刺激响应性、优异的热稳定性和光稳定性,1应该是非常有前途的一次写入多次读取光学数据存储介质的候选者。
A new Schiff-base1based on 4-N,N-dimethylaminoaniline salicylaldehyde is developed. It possesses unique solution-solid dual emission behaviour with emission color: an aggregation-induced bright turquoise emission in liquid and strong near-infrared emission in the solid state. Interestingly, on the one hand, compound1is promising a ratiometric fluorescent probe for Zn2+ions detection in the aqueous solution with high sensitivity, selectivity, and relatively low detection limit. On the other hand, based on its inner stimuli-responsive nature, outstanding thermostability and photostability,1should be a very promising candidate for the write-once read-many optical data storage medium.
