Synthesis, spectroscopic studies and nonlinear optical behavior of N,N '-bis(2-hydroxy-1-naphthylmethylidene)-1-methyl-1, 2-diaminoethane-N,N ',O,O '-nickel(II)
Özet
A Schiff base complex N,N'-bis(2-hydroxy-1-naphthylmethylidene)-1-methyl-1,2- diaminoethane-N,N',O,O'-nickel(II) has been synthesized. The title compound has been characterized by FT-IR and UV-vis spectroscopies. The UV-vis experiments indicate that the compound has solvatochromism in the UV region, implying non-zero molecular first hyperpolarizability. To investigate microscopic second-order nonlinear optical (NLO) behavior of the examined complex, the electric dipole moments (mu) and the first static hyperpolarizabilities (beta) were computed using Finite Field second-order Moller Plesset (FF MP2) perturbation procedure. According to ab initio quantum mechanical calculations, the title complex exhibits non-zero P values, revealing microscopic second-order NLO behavior.
