  Reversible, High Molecular Weight Palladium and Platinum Coordination Polymers Based on Phosphorus Ligands

  摘要：

  A general strategy for the preparation and characterization of high molecular weight coordination polymers based on bifunctional phosphorus ligands and palladium or platinum dichloride is described. Metal-to-ligand stoichiometry is of key importance for the formation of linear coordination polymers with high degrees of polymerization and was studied in detail. Heating of precursor complexes in the melt led to the highest degrees of polymerization. Peak molecular weights of 71000 g/mol were reached, corresponding to a degree of polymerization of 100 units. The coordination polymers based on palladium dichloride were demonstrated to be linear by performing a stopper experiment. Complexation with platinum resulted in the formation of a network polymer due to platinum's ability to coordinate three phosphorus atoms. The palladium coordination polymers form reversibly and are in equilibrium with rings. The concentration dependence of the ring-chain equilibria was studied for the palladium complexes with P-31 NMR and size exclusion chromatography, and critical concentrations of 70-180 mM were determined, below which no polymers are present.

  days at -20 degrees C. 31P NMR measurements on model complexes showed that the large differences in gelation times are in agreement with the ligand exchange kinetics of the rhodium(I) and iridium(I) complexes. We propose that sonication of the gels results in ligand exchange, which changes the network topology without changing the coordination chemistry. Upon sonication, the fraction of metal centers in

  通过将二苯基次膦酸盐遥爪聚四氢呋喃 (2) 与 [RhCl(COD)] 2 或 [IrCl(COD)] 2 在氯仿中结合制备可逆配位网络。对于铑(I) 和铱(I) 网络，这两种系统分别在高于50 和30 g/L 的浓度下产生稳定的凝胶。通过振荡剪切实验确定了两个配位网络 (100 g/L) 的流变特性，这表明弹性模量在很宽的频率范围内是恒定的，表明具有凝胶状行为；铱（I）凝胶的弹性模量（2.8x10（3）Pa）明显高于铑（I）凝胶（1.0x10（3）Pa）。铑（I）凝胶的超声处理在 3 分钟后引起液化；超声处理停止后 1 分钟发生再凝胶。在超声处理 3 分钟后，铱 (I) 凝胶也被液化，但再凝胶在室温下需要 1.5 小时，在 -20 摄氏度下需要 10 多天。对模型配合物的 31P NMR 测量表明，凝胶时间的巨大差异与铑 (I) 和铱 ( I) 复合体。我们建议凝胶的超声处理会导致配体交
