Metal-ion-mediated synergistic coordination: construction of AIE-metallogel sensor arrays for anions and amino acids

Abstract

Supramolecular gels with aggregation-induced emission (AIE) are recognized as excellent chemosensor. The combination of gelators and metal ions gives rise to a synergistic effect, which induces functional behaviors of anions...

Recent advances in aggregation-induced emission (AIE)-based chemosensors for the detection of organic small molecules

“…121 Yao and co-workers also synthesised metallogel A47 from 3,4,5-tris(hexadecyl) benzoyl hydrazine functionalized naphthalimide with various metal ions. Notably, A47 with Fe 2+ and Ni 2+ ions are able to selectively detect (L)-Trp to ultrasensitive levels 122 (Fig. 8a and b).…”

Supramolecular gels – a panorama of low-molecular-weight gelators from ancient origins to next-generation technologies

“…394 In elegant work, the solid-like nature of the gel enabled the fabrication of an array of fluorescent gel spots, allowing the detection of multiple analytes in parallel through an optical response mechanism, while the liquid-like nature of the gel enabled effective diffusion and rapid response to analytes. 395…”

Regulating Gelation and Luminescence Behaviors of Single Pyridine-Functionalized Cyanostilbene via Metal Ions

“…12,13 For example, the 3,4,5-tris(hexadecyl) benzoyl hydrazine-functionalized naphthalimide gelator can self-assemble into a stable organogel with blue-green fluorescence and then coordinate with different metal ions through coordination bonds to form a series of metallogels. 14 Moreover, the pyridine group is often used as a coordinating site in the gelators. The bidentate gelators 13,15 have been successively designed and synthesized by integrating the AIE units including diphenylanthracene or dithienylethene and terpyridine moiety through an amide linkage.…”
