A lead-free perovskite-like hybrid with above-room-temperature switching of quadratic nonlinear optical properties†
Abstract
We report a new lead-free perovskite-like hybrid, composed of hexamethyleneimine and one-dimensional [SbCl5]n2− polyanionic zigzag chains, which shows above-room-temperature switching of quadratic nonlinear optical (NLO) properties induced by the unique order–disorder conformational changes of the organic cation.
