The rapid growth in the field of metal-organic frameworks (MOFs) over recent years has highlighted their high potential in a variety of applications. For biological and environmental applications MOFs with low toxicity are vitally important to avoid any harmful effects. For this reason, Ca-based MOFs are highly desirable owing to their low cost and high biocompatibility. Useful Ca MOFs are still rare owing to the ionic character and large size of the Ca ion tending to produce dense phases. Presented here is a novel Ca-based MOF containing 2,3-dihyrdoxyterephthalate (2,3-dhtp) linkers Ca(2,3-dhtp)(HO) (SIMOF-4). The material undergoes a phase transformation on heating, which can be followed by variable temperature powder X-ray diffraction. The structure of the high temperature form was obtained using single-crystal X-ray diffraction. The electrochemical properties of SIMOF-4 were also investigated for use in a Na ion battery.
近年来，金属-有机骨架（MOFs）领域的快速发展凸显了它们在各种应用中的巨大潜力。对于生物和环境应用，具有低毒性的 MOFs 对于避免任何有害影响至关重要。出于这个原因，基于 Ca 的 MOFs 因其低成本和高生物相容性而备受青睐。由于 Ca 离子的离子特性和较大尺寸，有用的 Ca MOFs 仍然很少，这往往会产生密集的相。本文介绍了一种新型的基于 Ca 的 MOF，它含有 2,3-二羟基对苯二甲酸（2,3-dhtp）连接体 Ca(2,3-dhtp)(HO)（SIMOF-4）。该材料在加热时会发生相变，可以通过变温粉末 X 射线衍射进行跟踪。使用单晶 X 射线衍射获得了高温形式的结构。还研究了 SIMOF-4 的电化学性能，以用于钠离子电池。
