Probing Frontier Orbital Energies of {Co-9(P2W15)(3)} Polyoxometalate Clusters at Molecule-Metal and Molecule-Water Interfaces
Original language description
Functionalization of polyoxotungstates with organoarsonate coligands enabling surface decoration was explored for the triangular cluster architectures of the composition [Co-II (9)(H2O)(6)(OH)(3)(p-(RC6H4AsO3)-O-V)(2)(alpha-(P2W15O56)-W-V-O-VI)(3)](25-) ({Co-9(P2W15)(3)}, R = H or NH2), isolated as Na-25[Co-9(OH)(3)(H2O)(6)(C(6)H(5)ASO(3))(2)(P2W15O56)(3)]center dot 86H(2)O (Na-1; triclinic, P (1) over bar, a = 25.8088(3) angstrom, b = 25.8336(3) angstrom, c = 27.1598(3) angstrom, alpha = 78.1282(11)degrees, beta = 61.7276(14)degrees, gamma = 60.6220(14)degrees, V = 13888.9(3) angstrom(3), Z = 2) and Na-25[Co-9(OH)(3)(H2O)(6)(H2NC6H4AsO3)(2)(P2W15O56)(3)]center dot 86H(2)O (Na-2; triclinic, P (1) over bar, a = 14.2262(2) angstrom, b = 24.8597(4) angstrom, c = 37.9388(4) angstrom, alpha = 81.9672(10)degrees, beta = 87.8161(10)degrees, gamma = 76.5409(12)degrees, V = 12920.6(3) angstrom(3), Z = 2). The axially oriented para-aminophenyl groups in 2 facilitate the formation of self-assembled monolayers on gold surfaces and thus provide a viable molecular platform for charge transport studies of magnetically functionalized polyoxometalates. The title systems were isolated and characterized in the solid state, in aqueous solutions, and on metal surfaces. Using conducting tip atomic force microscopy, the energies of {Co-9(P2W15)(3)} frontier molecular orbitals in the surface-bound state were found to directly correlate with cyclic voltammetry data in aqueous solution.
