Abstract

Abstract : [ R -3-hydroxylpiperidinium]2 SbCl5 is a photoluminescent chiral lead-free organic–inorganic ferroelastic semiconductor showing switchable second-harmonic generation response and clear ferroelastic domains. Abstract : Chiral organic–inorganic hybrid semiconductors (COIHSs) dominated by lead halides have recently gained tremendous interest. Here, we report a lead-free photoluminescent COIHS [ R -3-hydroxylpiperidinium]2 SbCl5 with a bandgap of 3.14 eV. It shows a ferroelastic phase transition at 341 K accompanied by a switchable second-harmonic generation response and presents clear ferroelastic domains, which are rarely found in lead-free COIHSs.
