文摘

Two strategies have been explored for organic functionalizations of ZnO nanotetrapods via anchoring groups ofcarboxylate and phosphonate. With these methods, oleyl chains were assembled on the surfaces of the ZnO nanotetrapods,significantly enhancing their solubility in nonpolar solvents, such as chloroform and toluene. The surface functionalizationstrategies have been extended to electroactive and photoactive molecules such as protoporphyrin and C₆₀ on the ZnOnanotetrapods. The surface-modified ZnO nanotetrapods were characterized comprehensively, revealing a uniform,covalently linked monolayer assembled on the surface. This work opens a broad perspective for the application ofthe organically functionalized nanotetrapods in optoelectronics and biomedicine.
