    • Abstract

       

      The imino nitrogen of p-methoxybenzylideneimidazolinone (pMBDI) was protonated using aqueous HClO4 and HCl acid and crystallized in monoclinic crystal system with P21/n space group. Interestingly, the protonated compounds are fluorescent in polar solvents but non-fluorescent in non-polar solvent as well as in the solid state. These results point to the existence of a non-radiative pathway involving the imidazole nitrogen in the quenching of excited states in these compounds.
