Reversible Phase Transition and Second-Harmonic Response Based on a Zero-Dimensional Organic–Inorganic Hybrid Compound

Abstract

The organic–inorganic hybrid materials (OIHMs) with stimuli-responsive features show the important scientific attraction in a multifunctional material application field, such as optoelectronic memory and sensors. Especially, designing a functional material with both dielectric switching and second-harmonic generation (SHG) remains attractive. Herein, we report a new OIHM [C7H15NCl] SbCl4 as a phase matching nonlinear optical material and dielectric switch functional materials. It undergoes a reversible phase transition at 297 K and exhibit a harmonic generation (SHG) effect of about 0.53 times that of KH2PO4 (KDP). Meanwhile, it also possesses potential semiconducting properties. This work might provide a strategy for designing novel multifunctional materials in the field of crystals and dielectrics.
