Synthesis, crystal structure, and third-order nonlinear optical properties of a copper(I) one-dimensional coordination polymer [Cu(μ-1,1,1,3-N3)] n

Abstract

A novel copper(I) azide coordination polymer [Cu(μ-1,1,1,3-N3)]n has been synthesized by the low-temperature solution-state reaction. Crystal X-ray analyses reveal that compound [Cu(μ-1,1,1,3-N3)]n possesses a type of three-dimensional (3D) framework structure. The polymer was characterized by elemental analyses, IR spectra, and UV-Vis spectra. The third-order nonlinear optical (NLO) properties were also investigated, and they exhibit good linear absorption and self-defocusing performance with modulus of the hyperpolarizability (γ) 8.16 × 10−30 esu for [Cu(μ-1,1,1,3-N3)]n in a 1.96 × 10−4 mol dm−3 DMF solution.
