A ferroelectric inorganic–organic hybrid based on NLO-phore stilbazolium

Abstract

A ferroelectric inorganic–organic hybrid based on in situ substituted stilbazolium cation (TAMS²⁺ = trimethylamino-N-methyl stilbazolium) has been obtained. Single-crystal X-ray structure analysis demonstrates that the NLO-phore organic component of the complex is embedded into the inorganic polymeric [Bi₂Cl₈]²⁻ framework and shows a polar arrangement with the cooperation of the nonsymmetric inorganic component. The measurement of ferroelectric and nonlinear optical properties show typical ferroelectricity and second harmonic generation (SHG) responses as well as a significant improvement of the laser damage threshold and thermal stability of relative organic material.
