A new insight into the unique magneto‐optical effect of layered perovskite (C6H5C2H3FNH3)2MnCl4
2023
Overview
Magnet‐optical materials embracing coupled magnetic and photoluminescent properties in single phase are promising in microelectronics and optoelectronic devices. However, the current research mainly focuses on traditional inorganic materials, and there are few reports on molecule materials. Recently, we synthesized an organic–inorganic hybrid complex (C6H5C2H3FNH3)2MnCl4 (1) with perovskite structure. Physical measurements show that 1 not only behaves as an antiferromagnet with spin canting but also exhibits unusual fluorescent properties. Importantly, under the magnetic field at different temperatures, the luminous intensity of 1 changed, and a red‐shift occurred with obviously optical hysteresis. These phenomena directly prove the existence of magneto‐optical coupling in 1. More interestingly, the optical hysteresis can be observed in both low and high field, which is unprecedented in other molecular materials. Even in traditional inorganic materials, it can only be observed in strong field. This special function provides the possibility for the application of low energy consumption optoelectronic devices. This is the first coordination complex showing magneto‐luminescence. Besides, under different temperatures and applied magnetic fields, the title complex exhibits the unusual magneto‐fluorescence properties, in which the emission peak has an obvious red‐shift with the increasing magnetic field with a hysteresis loop even in low field. This special phenomenon provides the possibility for the application of low energy consumption optoelectronic devices.
