Abstract

Near-field scanning optical microscopy (NSOM) has been used to write and read images on a conjugated polymer film—such as that in the Figure–with a resolution of ∼ 0.1 μm, clearly breaking the diffraction limit. It is demonstrated that photo-oxidation processes produce the contrast and that NSOM has the potential to control the photochemistry of a conjugated polymer at the nanometer scale.
