Heteropolyoxometalates have garnered widespread attention owing to their diverse structures and intriguing physicochemical properties. Herein, we successfully synthesized a unique lanthanide-incorporated PIII–SbIII-heteroatom-templated tetrahedral polyoxometalate cluster [H2N(CH3)2]20Na7H7{[Er6(H2O)6][W4O16][HPSbW15O54]4}·132H2O (1). The polyoxoanion of 1 can be perceived as four trilacunary Dawson [HPSbW15O54]11– {PSbW15} building blocks encapsulating deca-nuclear heterometallic [Er6(H2O)6W4O16]10+ cluster. This comprises an inner [W4O16]8– ({W4}) core surrounded by octahedral [Er6(H2O)6]18+ ({Er6}) shell. Consequently, the exhibits distinctive ({W4} ⊂ {Er6} [{PSbW15}]4) three-shell structure. Considering electron transfer characteristics 1, it was coelectropolymerized with N-methylpyrrole (NMPy) fabricate 1–PNMPy film (PNMPy = polyNMPy). Notably, incorporation improves distribution within PNMPy backbone, thereby narrowing band gap enhancing conductive performance film. Therefore, is utilized modified electrode material construct electrochemical biosensor for sensitive detection tumor marker microRNA-155. research not only provides viable approach fabrication multishell heteropolyoxometalates but also promotes exploration application multicomposition polyoxometalates in biosensing microRNA.
