We disclosed that acetamidinium perchlorate is a plastic crystal undergoing a near-room-temperature plastic transition. Thanks to drastic symmetry breaking during the plastic transition, it displays remarkable nonlinear optical switching with a high on/off contrast and a superior reversibility, as well as rapid dielectric switching between the high and low dielectric states.
