Soft material with intense photoluminescence obtained by dissolving Eu2O3 and organic ligand into a task-specific ionic liquid

Abstract

A task-specific ionic liquid containing a carboxylate group with the ability to dissolve metal oxide and organic ligands has been used as the solvent to prepare lanthanide complexes without the addition of extra solvent; thus a soft material with intense photoluminescence has been obtained by directly dissolving Eu(2)O(3), 2-thenoyltrifluoroacetone (TTA) and 1,10-phenanthroline (Phen) into the task-specific ionic liquid.
