我们合成了一种溴桥钯配合物，通过X射线衍射分析、ESR、FT-IR和拉曼光谱证实，随着温度的降低，该配合物经历了电荷密度波（CDW）到Mott-Hubbard（MH）的相变。该复合物在很宽的温度范围内显示出具有条纹图案的相分离现象，并且使用光学显微镜观察到畴扩展。此外，我们还利用扫描隧道显微镜（STM）观察到了伴随相变的局域电子态的变化
We synthesized a bromo‐bridged Pd complex, which underwent as lowering the temperature a charge‐density‐wave (CDW) to Mott‐Hubbard (MH) phase transition, as confirmed by using X‐ray diffraction analysis, ESR, FT‐IR and Raman spectroscopies. The complex showed a phase‐separation phenomenon with a striped pattern over a wide temperature range, and domain propagation was observed using an optical microscope. Moreover, we observed changes in the local electronic state accompanying the phase transition by using scanning tunneling microscopy (STM)
