Template-Synthesized Polyacetylene Fibrils Show Enhanced Supermolecular Order

Abstract

We have recently described a template method for synthesizing nanoscopic conductive polymer fibrils. In this method, the pores in a nanoporous host membrane are used as templates for the nascent conductive polymer. We have shown that such template-synthesized fibrils show significantly higher conductivities than bulk films of the analogous polymer. We suggested that this enhanced conductivity results from preferential orientation of the polymer chain parallel to the fibril axis. This paper provides the first experimental proof for such enhanced supermolecular order in template-synthesized conductive polymer fibrils. We describe (for the first time) the template synthesis of nanoscopic polyacetylene fibrils. We demonstrate (using a polarized infrared absorption experiment) that the polymer chains in these fibrils are preferentially oriented parallel to the fibril axis. (js)
