Abstract

A novel bis-component AIE-gel TG was facilely constructed from two "easy-to-synthesize" tripodal gelators by a simple host-guest self-assembly process. Interestingly, the TG shows strong aggregation-induced emission (AIE) and could be used for highly efficient and sensitive detection and separation of ions (CN, Fe and HPO). The LODs (limits of lowest detection) of TG for CN, Fe and HPO are in the range of 4.93 × 10-7.80 × 10 M. Meanwhile, the xerogel of TG could adsorb and separate Fe from aqueous solutions, and the adsorption rate is 96%. In addition, a thin film based on the TG could act as a convenient test kit for the detection of CN and Fe. What is more, the TG-Fe film could not only be used as an erasable secure fluorescent display material, but also as a convenient reversible HPO test kit.

摘要

一种新型的双组分聚集诱导发光凝胶TG通过简单的主客体自组装过程，由两种“易于合成”的三脚架状凝胶剂轻松构建而成。有趣的是，TG表现出强烈的聚集诱导发光（AIE），可用于高效、灵敏地检测和分离离子（CN、Fe和HPO）。TG对CN、Fe和HPO的最低检测限（LOD）在4.93×10 - 7.80×10 M范围内。同时，TG的干凝胶能够从水溶液中吸附并分离Fe，吸附率为96%。此外，基于TG的薄膜可作为检测CN和Fe的便捷测试试剂盒。更重要的是，TG-Fe薄膜不仅可以用作可擦除的安全荧光显示材料，还可以用作便捷的可逆HPO测试试剂盒。
