Covalently grafted pyrene moieties onto the K₇[PW₁₁O₃₉]路13H₂O cluster (K₇-PW₁₁) results in the formation of a new organic/inorganic hybrid with the molecular formula of (Bu₄N)₄{(PW₁₁O₃₉)[O(Si(CH₂)₃NH鈥揅OOCH₂C₁₆H₉)₂]} (Py-PW₁₁), which has been immobilized onto single-walled carbon nanotubes (SWNTs) homogeneously via 蟺鈥撓€ stacking and electrostatic interactions. The resulting SWNTs/Py-PW₁₁ nanocomposite material exhibits excellent adsorption of human serum albumin (HSA), as evidenced by high-resolution transmission electron microscopy (HR-TEM) and X-ray photoelectron spectroscopy (XPS) studies. This work paves a new pathway for the development of polyoxometalate (POM)-based biomaterials.
