Near‐Room‐Temperature Synergetic Response of Magnetism, Dielectricity and Luminescence Based on (C5NH13Cl)2MnBr4

Multifunctional materials with working temperature near room temperature is crucial for practical application. Until now, it is still a great challenge to obtain such materials. In this paper, we synthesized a complex of (C5NH13Cl)2MnBr4 (1) with structural phase transition near room temperature. The phase transition further induces the switchable magnetic properties, dielectric anomalies and luminescent response at the same range of temperature. It is the first time to observe the synergetic effect of magnetism, dielectricity and luminescence near room temperature in the same molecular complex.
