Abstract

Optic-electric responsive materials have attracted much attention for their applications in temperature-sensing, actuators, and memory switches. However, it is a challenge to integrate various functions to form multifunctional responsive materials. As molecule-based hybrid materials usually consist of organic and inorganic components, the introduction of multiple functions can be achieved through structural construction. Thus far, even though full-temperature cover is required for device applications, full-temperature covered multi-switchable hybrid materials have rarely been successfully synthesized. Herein, the dynamic [(CH3)3NOH]+ cation and luminous center Mn(II) were introduced to form a hybrid material [(CH3)3NOH][MnCl3], showing multiple temperature-responsive behaviors. Upon temperature change, it exhibits multi-state dielectric switching response and intensity or peak shift response of luminous in full-temperature range (low, room, and high temperatures). These responsive behaviors are triggered by the motion or reorientation of [(CH3)3NOH]+ cations and inorganic framework. Overall, the switchable photoelectric material has potential applications in multiple encrypted storage and sensor devices.
