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 ZnCl2 and Zn(NO3)(2)center dot 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) < 2 (0.030), on the other hand in the solid state it varies in the order 2(0.034) < 1(0.69). Quenching of fluorescence intensity of 2 in the solid-state has been attributed to intense and extensive non-covalent interactions present in the crystal structure. Theoretical calculations, density functional theory (DFT) and time-dependent density functional theory (TD-DFT) were also performed to support the experimental findings. (C) 2017 Elsevier B.V.
