摘要

Optical-electrical duple bistable switches are those that enable simultaneous conversion of both optical and electrical signals in one device to realize seamless integration. Herein, imidazolium-FCrO3 can be prepared into a large-size single crystal and ultraflexible thin film with ultrahigh unidirectionality of (0 0 4) and is characterized through scanning electron microscopy (SEM), atomic force microscopy (AFM), powder X-ray diffraction, etc. Both the thin film and crystal display synchronously eximious optoelectronic duple characteristics (dielectric and nonlinear optical second harmonic generation (SHG) bistable switching ON/OFF), with a record-high SHG contrast of approximate to 250 (2.0 times that of KDP, potassium dihydrogen phosphate, exceeding all the known molecular materials/crystalline switches, revealing its potential to obtain high-efficiency signal-to-noise ratio), sensitive dielectric bistability, and remarkable switching antifatigue. These attributes make imidazolium-FCrO3 a potential candidate in photoelectric seamless integration devices and flexible multifunctional devices.
