Constructing hybrid films of conjugated oligomers and gold nanoparticles for efficient photoelectronic properties.
Hybrid films of conjugated oligomers and gold nanoparticles have been fabricated by a coordination approach on the surface of gold nanoparticles. This method facilitates mild linkage of the oligomer/nanoparticle layers in ambient conditions, which provides a general route for preparation of organic/inorganic interlayer superstructures. Characterization of the as-obtained hybrid film has been carried out by UV-vis absorption, fluorescence spectroscopy, and atomic force microscopy (AFM). The hybrid film exhibits dramatic changes in both optical and photovoltaic properties upon encapsulation of fullerene. A photoelectrical application is presented by taking electrochemical measurements of the self-assembled film. The results reveal potential technological uses in photovoltaic devices.
