Application Values of Two Cu(II) Schiff Base Coordination Complexes on Blue Fluorescent Materials.

Two Schiff base binuclear Cu(II) compounds, [Cu2(L)2·(H2O)2]·2DMF (1) together with its coordination polymer (CP) [Cu2(L)2·(4,4'-bpy)2]n (2) (H2L is 4-hydroxy-3-((2-hydroxy-5-mercaptobenzylidene)amino)-2H-chromen-2-one and 4,4'-bpy is 4,4'-bipyridine), were generated under an identical experimental environment in the absence and existence of auxiliary ligand 4,4'-bpy. Fluorescence spectroscopy testing shows that the ligand-based blue fluorescence emission offers potential for application as a blue photoluminescent material.
