我们报告了三（α-甲基吡啶胺）氯化铁（II）-乙醇络合物中光致相变的光晶体学研究。 X射线衍射数据显示原子尺度的结构重排伴随着低自旋相和高自旋相之间电子态的光稳态变化。通过观察域成核过程以及稳定相和光诱导相的共存，讨论了转变的动力学机制。
We report on a photocrystallography investigation of the photoinduced phase transition in the Tris(α-picolylamine)iron(II) chloride-ethanol complex. X-ray diffraction data show the structural rearrangement at the atomic scale accompanying the photosteady change of electronic state between the low-spin phase and the high-spin phase. The dynamical mechanism of the transformation is discussed with the observation of a domain nucleation process, with the coexistence of stable and photoinduced phases.
