One-Dimensional Perovskite with Ferroelectric and Switchable Nonlinear Optical Properties: [azetidinium]CdCl3 Organic-inorganic perovskite hybrids (OIPHs) have been a topical area of interest in recent years. This stems from their key features such as facile and inexpensive solution based synthesis, high mechanical flexibility, structural tuneability, and chemical diversity, to name a few.

A multiaxial electrical switching in a one-dimensional organic-inorganic (pyrrolidinium)2Cd2I6 ferroelectric and photoluminescent crystal Ferroelectric materials exhibiting more than one polar phase are very attractive in terms of application. The advantage of such materials is temperature-dependent switching between two different ferroelectric states. Here we report on the discovery of a unique, continuous ferroelectric – ferroelectric transformation in (C4H10N)2[Cd2I6], PCdI at 220 K.
