Synthesis, Structures and Characterization of Trisphosphonate- Containing Lanthanide Coordination Polymers
摘要
本論文研究為將含有三磷酸基的有機配子1,3,5-tris(methylene phosphonic acid)-2,4,6-trimethyl benzene (Me3-H6btmp)與三價鑭系金屬離子（Ce3+、La3+、Gd3+、Tb3+、Nd3+），利用室溫自組裝方式，在調控酸鹼的條件下，製備得到5種含三磷酸的有機-無機金屬之配位聚合物，並針對所合成的5種有機–無機配位聚合物(metal–organic coordinateon polymer)，作結構與物性上的探討。 在室溫自組裝條件下，有機配子(Me3-H6btmp)與三價鑭系金屬離子(Ce3+, La3+)反應分別得到等結構的三維配位聚合:{[Ln(Me3-H3btmp)(H2O)2]
並列摘要
In this thesis, 1,3,5-tris(methylene phosphonic acid)-2,4,6-trimethyl benzene (Me3- H6btmp), was selected as ligand to react lanthanide ions under ambient temperature to produce coordination polymers. Self-assembly of lanthanide ions with Me3-H6btmp in wate offorded 3D framewo- rks with a general formula {[Ln(Me3-H3btmp)(H2O)2]•H2O}n [Ln = Ce3+(1) ，La3+ (2)]. Compound {[Gd(Me3-H3btmp)]•4H2O}n (3) is a 1D helical coordination ion polymer, and compound{[Tb(Me3-H3btmp)]•4H2O}n (4) adopts a 1D zigzag chain. The structure of {[Nd4(Me3-H3btmp) 4(H2O)8]•4H2O}n (5) was found to be a 3D coordination polymer. The structures of coordination polymers 1–5 were characterized by single- crystal X-ray diffraction analysis and their physical properties were examined.
