Abstract

A novel supramolecular aggregation induced emission (AIE) π-gel (ONT) was constructed by using a functionalized trimesic amide (TCP) molecule assembled with a bis-pyridine functionalized naphthalene diimide (ND) molecule using a non-covalent interaction. The ONT showed strong AIE at 468 nm. Furthermore, the ONT could detect and adsorb ferric (Fe) or cupric (Cu) ions from water. Meanwhile, a thin film based on supramolecular AIE π-gel ONT was prepared, which could be used as a fluorescent security display material for detecting Fe or Cu. Thus, the AIE π-gel ONT shows potential for practical applications in efficient multi-analyte detection and separation and as a fluorescent display material.

摘要

通过使用功能化的均苯三甲酰胺（TCP）分子与双吡啶功能化的萘二酰亚胺（ND）分子通过非共价相互作用组装，构建了一种新型的超分子聚集诱导发光（AIE）π-凝胶（ONT）。ONT在468nm处表现出强烈的AIE。此外，ONT可以从水中检测和吸附铁（Fe）或铜（Cu）离子。同时，制备了基于超分子AIE π-凝胶ONT的薄膜，其可用作检测Fe或Cu的荧光安全显示材料。因此，AIE π-凝胶ONT在高效多分析物检测与分离以及作为荧光显示材料方面具有实际应用潜力。
