摘要
本文用水热法合成得到一个六元瓜环(Q[6])与一氯三水(4-吡啶甲酸)合镉(Ⅱ)配位聚合物自组装作用形成的超分子自组装体Q[6]·[Cd(H_2O)_3Cl(4-PCA)]_2·22(H_2O)。自组装体的形成源于瓜环的外壁作用,即Q[6]正电性静电势外壁与配位聚合物中4-吡啶甲酸吡啶环和配位Cl^-离子间的超分子相互作用,以及配位聚合物镉(Ⅱ)离子上配位水分子与瓜环端口羰基氧原子间的氢键作用。该自组装体对溶液中染料具有吸附作用和光催化降解的性能。
In this paper,a supramolecular self-assembly{Q[6]·[Cd(H 2O)3Cl(4-PCA)]2·22H 2O}comprising cucurbit[6]uril(Q[6])and a 4-pyridine carboxylic acid(4-PCA)and cadmium(Ⅱ)coordination polymer was synthesized with hydrothermal method.The formation of the supramolecular self-assembly was driven by the outer surface interaction of cucurbit[n]uril,which is the supramolecular interactions between positive electro-potential of the outer surface of Q[6]with pyridine ring and Cl-anion in the coordination polymer,and hydrogen bonding interaction between water molecules and the portal carbonyl oxygens atoms of Q[6].The self-assembly entity has the properties of adsorption and photocatalytic degradation of dyes in solution.
