有机膦酸多孔配合物的自组装和性质研究

Metal phosphonate chemistry has been of great interest in recent years,owing to its potential applications in ion exchanges, selected catalysis and sensors etc. The target of this project is to design and synthesize novel metal phosphonate compounds with porous structures and to study their chemical and physical properties. Following this target, we have investigated systematically the influences of various experimental conditions on the structures of metal phosphonates, based on 1-hydroxyethylidenediphosphonate (hedp). Our efforts have been especially focused on the template effects on the self-assembly of porous structures of metal-hedp compounds. More than fourty new compounds have been prepared and characterized, which have one-, two- and.three-dimensional structures. Among these, about 18 compounds exhibit structures with channels. Further,serveral other phosphonate ligands especially those with functional groups have been synthesized, and their coordination capabilities explored. Finally, systematic studies on the magneto-structural relationship of these compounds have been conducted. The ion-exchange properties of a few compounds have been investigated.

合成新颖的配合物型分子筛类似物是一个崭新的研究领域，本项目将致力于合成新的有机膦酸多孔配合物，系统地研究各种反应条件对产物结构的影响，特别是模板试剂对多孔结构自组装的向导作用，最终指导并实现有机膦酸多孔配合物的定向设计与合成。研究这类多孔结构与客体分子间的相互识别作用，以及结构与性能之间的关系，进一步探索功能型有机膦酸多孔材料具有重要的理论和实际意义。. ..
