The multifunctionalization of spin-crossover molecular materials is a research hotspot in the field of molecular magnetism, providing insights into the design and synthesis of multifunctional materials by coupling and controlling their magnetic, dielectric, fluorescence, and ferroelectric properties. Hofmann-type metal-organic framework structures serve as carriers, offering advantages in coupling and controlling spin-crossover and dielectric functionalities. Recently, our research group successfully utilized K2[M(CN)4], (3,4-di-4-pyridyl)thiophene, and FeII ions for self-assembly, obtaining two examples of coordination polymers {Fe(3,4-bpt)2[M(CN)4]} (M= Pt, Pd) with hysteresis-type magnetic-dielectric bistable behavior. Additionally, we achieved photo-reversible control over their magnetic bistability, enabling these compounds to exhibit multi-channel transformations in terms of magnetism, electricity, structure, and thermochromism. This work provides new avenues for developing multifunctional materials with hysteresis-type magnetic-dielectric bistable behavior.
