Hierarchical crystalline superstructures of conducting polymers with homohelicity

摘要

(Figure Presented) Tuning hierarchical superstructures of helical nanofibers: Helical conducting polyaniline (PANI) nanofibers can self-assemble into linear nanofibers, branched nanofibers, and microribbons by controlling their aggregation processes. Structural studies indicated that helical PANI molecules are arranged normal to the long axis of nanofibers, which is very similar to the arrangement of peptides in β sheets (see figure).
