Defect dicubane 3d/Dy(III) Coordination Clusters: Heading for materials displaying catalytic properties

本项目旨在合成一系列具有缺陷双立方烷拓扑结构的具有官能化Schiff碱配体的等骨架四核3D/Dy(III)CCS，并研究其在催化中的应用。席夫碱连接物将与二价过渡金属和Dy(III)离子一起用于合成CCS。取代的邻香草醛分子将与2-氨基酚或对映体纯的2-苯基甘氨酚偶联，合成有机席夫碱连接物。当这些配体与二价过渡金属和三价稀土离子结合时，合成了具有缺陷双立方烷拓扑结构的四核CCS。靶向CCS将作为催化剂用于不同的Lewis酸催化的有机反应。这些化合物的催化活性将在质子和非质子体系中进行研究。这是利用3D/Dy CCS作为催化剂的一种新方法，这将是首次研究。

This project seeks to synthesize a series of isoskeletal tetranuclear 3d/Dy(III) CCs possessing a defect dicubane topology, with functionalized Schiff base ligands and investigate their use in catalysis. The Schiff-base linkers will be employed along with divalent transition metal and Dy(III) ions for the synthesis of CCs. Substituted o-vanillin molecules will be coupled with 2-aminophenol or enantiomerically pure 2-phenylglycinol to synthesize organic Schiff Base linkers. The proposed ligands when combined with divalent transition metal and trivalent lanthanide ions result in the synthesis of tetranuclear CCs possessing defect dicubane topology. The targeted CCs will be used as catalyst for different Lewis-acid catalysed organic reactions. The catalytic activity of those compounds will be studied in protic and non-protic systems. This is a new approach of using 3d/Dy CCs as catalysts, and will be studied for the first time.
