通过Wells-Dawson型Ta/W混合配位体POM与镧系离子的自组装，得到了4个含Ta的POM的镧系衍生物[Ln 3（H2O）22][P2 W15 Ta 3 O 62]·nH 2 O（Ln = La，1; Ce，2; Pr，3; Nd，4）.化合物1在高相对湿度（RH）下显示出优异的质子传导性能，在95 °C和98%RH下的电导率达到1.26 × 10−2 S cm−1。
Four lanthanide derivatives of Ta-containing POMs [Ln3(H2O)22][P2W15Ta3O62]·nH2O (Ln = La, 1; Ce, 2; Pr, 3; and Nd, 4) were isolated by the self-assembly of Wells–Dawson type Ta/W mixed-addendum POM and lanthanide ions. Compound 1 showed excellent proton conduction performance at high relative humidities (RHs), with conductivity reaching 1.26 × 10−2 S cm−1 at 95 °C under 98% RH.
