A tripodal acylhydrazone derivative (L) was designed, synthesized, and fully characterized. Through the investigation, it had a typical bluish-green aggregation-induced emission (AIE) effect. Notably, the gelator was reported to accurately detect Al3+ via emitting brilliant green light and decay by oxalic acid, and the detection limit of the sensor for Al3+ was 8.702 × 10−7 M. Interestingly, the fluorescence intensity of gelator L would change depending on the water fraction in DMF or DMSO solution. Furthermore, L could detect Fe3+, Fe2+, and Ag+ through a change in colour or gel phase. Accompanied by colour and fluorescence changes, we hope to provide a useful and effective strategy for preparing novel sensing soft materials.

设计,合成并充分表征了三脚架酰基hydr衍生物(L)。通过调查,它具有典型的蓝绿色聚集诱导发射(AIE)效果。值得注意的是,胶凝剂报道精确地检测的Al 3+ 通过由草酸发射辉煌绿光和腐烂,所述传感器为Al的检测限3+为8.702×10 -7有趣M.,胶凝剂的荧光强度大号会根据DMF或DMSO溶液中水的含量而变化。此外,L可以检测到Fe 3+,Fe 2+和Ag +通过改变颜色或凝胶相。伴随着颜色和荧光的变化,我们希望为制备新型传感软材料提供有用和有效的策略。
