The solvothermal reaction of metal ions and D-H3pmpc yield three phosphonate-based metal-organic coordination polymers, {Cu(D-Hpmpc)(CH3OH)}n (PMOCP 1), {Cu(D-Hpmpc)}n (PMOCP 2), {Cd2(D-pmpcH)(H2O)2Cl2}n (PMOCP 3) with diversified coordination fashions and dimensional features (D-H3pmpc = (D)-1-(phosphono-methyl)piperidine-3-carboxylic acid). PMOCP 1 exhibits a right-handed helical chain with a pitch of 6.785 Å and interchain O–HO hydrogen-bond. PMOCP 2 displays a chiral 2D network with (4, 4) topology and 1D O–HO hydrogen-bond chain. PMOCP 3 shows a non-interpenetrating diamondoid architecture and various hydrogen-bond interactions. Their chiralities are testified by vibrational circular dichroism spectroscopy and second-order nonlinear optical response measurements. Compared with PMOCPs 1−2, PMOCP 3 has a high water stability, a moderate proton conductivity of 9.87×10-5 S cm-1 at 298K and ~97% RH and a lower activation energy of 0.14 eV.

由对映纯有机磷酸酯衍生的一维,二维和三维金属有机配位聚合物:同质性,水稳定性和质子传导

金属离子与D-H3pmpc的溶剂热反应产生了三种基于膦酸酯的金属有机配位聚合物{Cu(D-Hpmpc)(CH3OH)} n(PMOCP 1),{Cu(D-Hpmpc)} n(PMOCP 2 ),{Cd 2(D-pmpcH)(H 2 O)2 Cl 2} n(PMOCP 3),具有多种配位方式和尺寸特征(D-H3pmpc =(D)-1-(膦酰基-甲基)哌啶-3-羧酸)。PMOCP 1展示了一个螺距为6.785Å的右旋螺旋链和链间O–HO氢键。PMOCP 2显示具有(4,4)拓扑和1D O–HO氢键链的手性2D网络。PMOCP 3显示了非互穿的类金刚石结构和各种氢键相互作用。通过振动圆二色光谱和二阶非线性光学响应测量证明了它们的手性。与PMOCP 1-2相比,PMOCP 3具有较高的水稳定性,
