摘要

监测配位聚合物的组装过程对于阐明配位聚合物的组装机理和开发具有明确结构和功能的新型配位聚合物至关重要。本文以离散的{Mn4}簇为原料，经热脱水法制备了{Mn2-1D}一维配位聚合物。通过单晶/粉末x射线衍射（SC/P-XRD）、红外光谱和拉曼光谱对热致增维过程进行了监测。此外，还研究了CPs的增强磁热性能。在增维过程中，磁熵变化值从{Mn4}中的26.92 J K - 1kg -1增加到{Mn2-1D}中的36.78 J K - 1kg -1 （T = 2 K， ΔH = 7 T）。

Thermotropic Approach from {Mn4} Cluster to One-Dimensional Coordination Polymer: Structure Conversion and Enhanced Magnetocaloric Effect

Monitoring the assembly process of coordination polymers (CPs) is crucial for elucidating the assembly mechanism and developing new CPs with well-defined structures and functions. In this paper, a one-dimensional coordination polymer of {Mn2-1D} have been constructed from discrete {Mn4} clusters, along with thermal dehydration. The thermotropic dimension augmentation process was monitored via single crystal/powder X-ray diffraction (SC/P-XRD), infrared spectroscopy and Raman spectroscopy. Additionally the enhanced magneto-thermal properties of CPs were investigated. During the dimension augmentation, the magnetic entropy change values increased from 26.92 J K^–1kg^–1 in {Mn4} to 36.78 J K^–1kg^–1 in {Mn2-1D} (T = 2 K, ΔH = 7 T).
