摘要
在常规水溶液中成功合成了一例芳香族有机膦酸修饰的有机-无机杂化磷钨酸盐--K4Na4H11[KCo2(H2O)10P4W24O92{(PhPO)2]-48H2O (1)。其突出的结构特征是[KP4W24O92{(PhPO)2]]23-的整体结构类似于一个 V 型结构，由两个[Co(H2O)5]2+ 离子稳定。此外，它还可以通过 K+ 离子连接成三维网状结构。令人惊讶的是，1 在 95% RH、318 K 条件下具有 1.59 × 10-2 S cm-1 的惊人高质子电导率，这可能是由于其结构中含有大量的晶格水、配位水和反阳离子。
A Dawson-type {P4W24} modified using phenylphosphonic acid with excellent proton conductivity†
A case of organic–inorganic hybridized phosphotungstate modified using aromatic organophosphonic acid, K4Na4H11[KCo2(H2O)10P4W24O92{(PhPO)2}]·48H2O (1), was successfully synthesized in conventional aqueous solution. The prominent structural feature is that the total structure of [KP4W24O92{(PhPO)2}]23− resembles a V-shaped structure, which was stabilized by two [Co(H2O)5]2+ ions. Furthermore, it can be connected into a three-dimensional mesh structure using K+ ions. Surprisingly, 1 possesses a remarkably high proton conductivity of 1.59 × 10−2 S cm−1 at 95% RH and 318 K probably due to the fact that its structure contains large amounts of lattice water molecules, coordination water molecules and counter cations.
