Regulating Circularly Polarized Light Detection via Polar-Phase Transition in Alternating Chiral-Achiral Cations Intercalation-Type Hybrid Perovskites.

ABSTRACT: Circularly polarized light (CPL) detection has wide applications in many fields, where the anisotropy factor (g_Iph ) is an important indicator to characterize the CPL detection performance. So far, many materials with high g_Iph have been reported, however, the exploration of the regulation of g_Iph is still in its infancy. Herein, two novel alternating chiral-achiral cations intercalation-type chiral hybrid perovskites (CHPs), named (R/S-1-phenylpropylamine)(propylamine)PbBr₄ (1-R/S), exhibit above room-temperature (RT) polar-phase transition, which greatly regulates the g_Iph value. The g_Iph of 1-R is 0.04 in high-temperature phase chiral non-polar (P2₁ 2₁ 2₁ ) by applying 5 V bias, interestin
