Synthesis, characterization and photophysical studies of zinc(II) complexes derived from a hydralazine hydrazone

Abstract In the present study, we report two novel mononuclear zinc(II) complexes (1 and 2) obtained by reacting ( E )-1-(phenyl(pyridin-2-yl)methylene)-2-(phthalazin-1-yl)hydrazine (L) with ZnCl 2 and Zn(NO 3 ) 2 ∙6H 2 O respectively. Photophysical properties of the compounds were studied in both solution and solid phase. The fluorescence absolute quantum yield of the complexes in solution varies in the order 1 (0.01)
