Abstract
An electro-optical modulator was constructed using a DNA nanostructure scaffold with oligomers of poly(phenylenevinylene) and polyaniline. A molecular device containing one each of the functional molecules was assembled in a DNA origami. The constructs formed an "X" shape and were visualized by atomic force microscopy. In response to redox reconfiguration, the device reversibly altered fluorescence signal output. This molecular self-assembly strategy provides opportunities to make unique material composites that are difficult to achieve by blending. The strategy offers a "plug and play" format that may lead to many new functions.
