New publication in Chemical Communications


A sample of the naphthalimide-based hydrogel

Congratulations to Chris and Amy from the TG group, as well as collaborators Kevin Byrne and Prof. Wolfgang Schmitt (TCD School of Chemistry and CRANN) and Dr Gavin Ryan and Prof. Matthias Möbius (TCD School of Physics) for their recent publication in Chemical Communications entitled “A resilient and luminescent stimuli-responsive hydrogel from a heterotopic 1,8-naphthalimide-derived ligand”. This work describes the synthesis of a fluorescent naphthalimide-containing gelator which forms robust hydrogels in the presence of potassium ions. As well as a rare example of a hydrogelator containing no hydrogen bond donors, this material exhibits the useful property of chemical reversibility, where 18-crown-6 and potassium chloride can be used to disrupt or re-form the gel, respectively.
