Synthesis and nonlinear optical study of the hybrid salt: [C12H14N2][Fe(CN)5(NO)]⋅5H2O

Abstract

The new prepared hybrid salt 1,1’-(Ethylene-1,2-diyl)dipyridinium pentacyanidonitrosoferrate(II) pentahydrate was synthesized. Then, it was characterized using different spectroscopic methods. The nonlinear optical properties of the new compound were investigated using the simple [Formula: see text]-scan technique with a CW diode laser radiation ([Formula: see text][Formula: see text]nm). Also, the [Formula: see text]-scan technique with pump/probe configuration was utilized to observe the Cross Phase Modulation (XPM) phenomena. Theoretical fit to the new experimental data was performed to calculate the third order nonlinear optical parameters including the nonlinear refractive index, which is about [Formula: see text][Formula: see text]cm2/W. This kind of molecule is considered to be promising candidate for using in future optoelectronic devices.
