Abstract

Hybrid diimidazolium-based ionogels were obtained bydispersing nitrogen-doped carbon nanodots (NCNDs) in ionic liquid(IL) solutions and by using dicationic organic salts as gelators. Theproperties of the NCND-ionogels were studied in terms of thermalstability, mechanical strength, morphology, rheological, and microscopicanalyses. Insights into the formation of the hybrid soft materialwere attained from kinetics of sol−gel phase transition and fromestimating the size of the aggregates, obtained from opacity andresonance light-scattering measurements. We demonstrate that, on onehand, NCNDs were able to favor the gel formation both in the presenceof gelating and nongelating ILs. On the other hand, the gelatinous matrix retains and, in some cases, improves theproperties of NCNDs. The NCND-ionogels showed the typical fluorescence emission of the carbon dots and a notableantiradical activity, with higher efficiency as compared to the single components. The presented hybrid materials hold great promise for topical applications in antioxidant fields.
