Abstract:

A mono-ligand neutral Mg (II) complex of a Schiff base ligand derived from 1-acetyl-2-naphthol and 4, 4’-diaminodiphenylmethane was prepared and characterized. The Schiff base acts as a double, negatively charged quadridentate ligand forming stable neutral Mg (II) complex. The luminescent characterizations of the Mg (II) complex material in solid and in organic solvents show that the Mg (II) complex has strong luminescent emission at ca. 452 nm when excited at 323 nm. The Mg (II) complex synthesized may be an excellent luminescent material.
