A D–A–D cationic cyclopentadienyl iron complex containing double arylazo chromophores (Fc-diazo) with methoxyl group (Fc-diazo-OMe) was obtained via nucleophilic substitution and well characterized by IR, UV–visible, 1H NMR, and 13C NMR spectroscopy, and MS. UV–Vis absorption and nonlinear optical property of Fc-diazo-OMe were investigated by comparison of Fc-diazo with no methoxyl group (Fc-diazo-H). Quantum chemical calculations of the orbital energy, geometric structure of Fc-diazo-OMe, and Fc-diazo-H were conducted by using density functional methods at the B3PW91/Lanl2dz level. Charge transfer from the highest occupied molecular orbital to the lowest unoccupied molecular orbital was found based on density functional theory. The substitution of the methoxyl group greatly improves the NLO property of Fc-diazo. Fc-diazo-OMe shows effective two-photon absorption, coefficient and third-order nonlinear susceptibility for potential applications as optical materials, while Fc-diazo-H barely shows NLO ability.
