Fluorescent carbon dot–molecular salt hydrogels.

Cayuela, Angelina and Kennedy, Stuart R. and Soriano, M. Laura and Valcárcel, Miguel and Steed, Jonathan W. (2015) 'Fluorescent carbon dot–molecular salt hydrogels.', Chemical science., 6 (11). pp. 6139-6146.

Abstract

The incorporation of functionalised carbon nanodots within a novel low molecular weight salt hydrogel derived from 5-aminosalicylic acid is reported. The carbon dots result in markedly enhanced gelation properties, while inclusion within the hydrophobic gel results in a dramatic fluorescence enhancement for the carbon nanomaterials. The resulting hybrid CD gels exhibit a useful sensor response for heavy metal ions, particularly Pb2+.
