Abstract
A novel ionic supramolecular gel (is-G) is synthesized using N-(pyridinium-4-yl)-naphthalimide (G1) and n-pentanoic acid. By rationally introducing competitive coordination into is-G, two ion coordinated ionic supramolecular gels is-IG and is-FeG (coordinated with I<sup>-</sup> and Fe<sup>3+</sup>, respectively) are obtained. is-IG could fluorescently "turn-on" detect Hg<sup>2+</sup> and l-Arg with specific selectivity, whereas, is-FeG could accurately identify l-Ser via fluorescence in water. Moreover, ion or amino acid responsive films based on these ionic supramolecular gels are prepared. These ionic supramolecular gels and films could act as multi-analyte detection materials as well as fluorescent display materials.
