Abstract

Abstract: Nonlinear optical (NLO) switches driven by a solid‐state structural phase transition have attracted extensive attention; however, above‐room‐temperature solid‐state NLO switch materials are still sparse. Herein, we report an above‐room‐temperature tin halide organic–inorganic hybrid quadratic NLO switchable material, N ‐methylpyrrolidinium trichloride stannite ([C5 H12 N]SnCl3, MPSC). The MPSC crystal exhibits a phase‐matchable NLO property that is 1.1 times that of KH2 PO4 (KDP) and NLO switching behavior, changing from a high second harmonic generation (SHG) response to a low SHG response at 383 K, thereby demonstrating its prospective applications in the field of nonlinear optics. Variable‐temperature crystal structural analysis combined with theoretical calculations revealed that the large NLO response stems from the inorganic SnCl3 moiety, whereas the high‐performance NLO switching properties mainly originate from the order/disorder transformation of the N ‐methylpyrrolidinium. This work provides a new approach to designing and exploring new high‐performance quadratic NLO switches involving tin halide organic–inorganic hybrids. Abstract : It's a switch ! Above‐room‐temperature quadratic NLO switchable material based on a Sn‐halide based organic–inorganic hybrid, N ‐methylpyrrolidinium trichloride stannite ([C5 H12 N]SnCl3, MPSC; see figure).
