Abstract

Herein, we describe the spectroscopic properties of “DNA-templated polyaniline nanoropes” self-assembled from DNA/
polyaniline complexes formed by the photo polymerization of aniline dimers in the presence of tris(2,2’-bipyridyl)ruthenium(II)
as a photo catalyst. The products of the photo polymerization reaction were pH-dependent however, the progress of the reaction
was curtailed in the higher pH region, and only oligomer formation was observed. In the lower pH region (pH 3.0), the photo
polymerization reaction yielded an emeraldine salt with a conductive polyaniline structure.
