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

Two Schiff base binuclear Cu(II) compounds, [Cu(L)·(HO)]·2DMF (1) together with its coordination polymer (CP) [Cu(L)·(4,4'-bpy)] (2) (HL 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.
