Abstract

Abstract : Four lanthanide derivatives were isolated by the self-assembly of {P2 W15 Ta3 O62 } and lanthanide ions, which showed good proton conduction performance. Abstract : Four lanthanide derivatives of Ta-containing POMs [Ln3 (H2 O)22 ][P2 W15 Ta3 O62 ]· n H2 O (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. Compound1 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.
