Abstract
A new acylhydrazone-functionalized dual benzimidazole derivative gelator (L) was synthesized. L can self-assemble in DMSO-EG (ethylene glycol) or DMF-water mixtures to form a thermo-responsive supramolecular organogel (L-gel). In order to increase the fluorescence intensity of L-gel (DMSO-EG system), L-gel slowly turned into a clear solution upon addition of one equivalent of RE (rare earth) Y<sup>3+</sup>. Interestingly, this gelator L and Y<sup>3+</sup> can be assembled into an enhanced blue-light-emitting supramolecular metallogel (Y@gel) in DMF-water mixtures.
