摘要(Abstract)：

本研究旨在合成3种具有高相变温度的零维有机-无机杂化金属卤化物，并系统探讨其相变特性及其调控机制.采用自然挥发法，以N-乙基吗啉作为有机配体，通过在无机组分中引入不同金属离子(Mn、Co、Zn),有效调控晶格内的分子间作用力.不同金属离子的引入使得N-H…Br氢键的键长逐渐缩短，从2.883?减小至2.860?,进一步缩短至2.769?,从而增强了有机-无机界面间的相互作用，显著提高了相变温度.具体而言，合成的化合物依次在432 K/375 K、452 K/394 K和457 K/398 K附近发生了可逆相变，展示出显著的热稳定性和相变特性.通过金属离子的选择和配位效应，成功调控了有机-无机杂化材料的相变行为.该研究为设计高相变温度的有机-无机杂化化合物提供了新的思路，并推动相关功能材料的进一步发展.
