摘要：The organic cations based on perylene diimide skeleton was employed to encapsulate H-3 [PW12O40], K-5[Eu(SiW11O39)], Na-9[EuW10O6] to construct organic-polyoxometalates hybrids by electrostatic interaction. We studied the ionic self-assembly of hybrids in ethanol/water mixed solution under fluorescence microscope and scanning electron microscopy. Layered-packing modes in solid state were explored by high-resolution transmission electron microscopy. Charge transfer properties of hybrids between organic donors and POM5 acceptors within the molecules were studied by solid diffuse reflectance spectroscopy. Hybrids can form colorful multi lamellar vesicles with different morphologies and show the typical charge transfer characteristics. The comprehension for the self-assembly morphology and solid structure of organic-polyoxometalate hybrids would help us to use easily modified organic moiety and functional inorganic polyoxoanions as blocks to build novel and giant supramolecular architecture.
