摘要
Eight new organo polyoxoinetalate charge transfer complexes (DH)\-6X\-2W\-\{18\}O\-\{62\}·(solv)\-n(D=Oxin(8 hydroxyquinoline), Py(Pyridine), Tol(toluene), A(aniline), DMA (N,N dimethyaniline), DEA(N,N diethylaniline), X=P, As; solv=DMF, H\-2O) was synthesized and characterized by using elemental analysis, IR, ESR. Polarographly, CV. Conductivity measurement, and X ray circle diffraction. The results showed that the crystal of (H\-2quinH)\-6P\-2W\-\{18\}O\-\{62\}·20H\-2O is Triclinic Crystal System, Space group \%P\{1-\}\%, with \%a=1.4659(5), b=2.045(8), c =2.1153(4) nm, α=90.01(3), β=87.95(2), γ=89.05(3)°, V =6.3393(35) nm\+3. This shows that under the irradiated title compound charge transfer between the organic donor and polyoxometalate anion has taken place.\;Polargraphy and cyclic Voltammetry show that the (H\-2quinH)\-6P\-2W\-\{18\}O\-\{62\}·20H\-2O undergoes three one electron reversible reduction steps in aqueous solution and four one electron quasi reversible reduction in DMF. Room temperature Conductivities of eight the title compounds ranging from 1.2×10\+\{-8\} to 3.6×10\+\{-9\} S·cm\+\{-1\} showed weak semiconducting behaviors.
