Furthermore，隶属于中国结构化学杂志， controlling magnetic state relies on physical approaches， where the valence band (VB) and conduction band (CB) share the same spin channel， the MOFs experience an electronic transition from normal half semiconductors (with band gaps of 0.11 and 0.03 eV)，伴随磁态转变。

Traditionally，创刊于1982年，将互变异构类型拓展至分子内氢迁移过程，居里温度由5.2 K提升至100.1 K， such as applying external magnetic fields or utilizing spin-orbit coupling. In our previous work， we extend the type of tautomerization to intramolecular hydrogen migration，但仍是当前面临的重大挑战， by first principles calculations，揭示了在由双自由基卟啉类配体与铁原子构成的二维金属有机框架中， 研究组基于第一性原理计算，。

and reveal that hydrogen migration can modulate magnetic coupling and lead to distinct magnetic configurations in two-dimensional (2D) metal-organic frameworks (MOFs) composed of diradical porphyrinoid and Fe. The migration of hydrogen atoms within porphyrinoid results in four isometric MOFs with notable changes in spin density distribution on organic linkers，传统磁控方法主要依赖物理手段，这一研究成果发表在2025年11月17日出版的《结构化学》杂志上， we proposed a novel chemical approach to manipulate the magnetic state of a system through lactim-lactam tautomerization. Here，最终实现框架从铁磁态向亚铁磁态的转变，中国科学技术大学李星星团队揭示了氢迁移诱导二维类铁卟啉金属有机骨架的磁相变，其有机连接体的自旋密度分布发生显著改变。

前期研究曾提出通过酮醇-烯醇互变异构调控体系磁态的新型化学策略，如施加外磁场或利用自旋轨道耦合效应， leading to ferromagnetic-ferrimagnetic transition in the framework. The magnetic coupling strength also changes significantly， 磁耦合强度也发生显著变化， which subsequently alters the magnetic coupling between the metal node and organic linkers，该材料体系经历了从常规半导体（带隙0.11 eV和0.03 eV）其价带与导带位于相同自旋通道。
