Abstract

A one-dimensional pattern-forming state of a cholesteric liquid crystal (CLC) is used as a template for the self-organization of ordered, spatially orientated, acetylene-based semiconducting polymers. The polymers are formed by metathesis reaction with all chemical components contained in an ordinary electro-optic cell. The polymer morphology consists of parallel ∼ 1 μm thick bundles, uniformly spaced at ∼ 10 μm over the full macroscopic active area of the cell substrates. The polymer templating can be explained by a model that predicts a corrugation in polymer density determined by the spatially periodic profile of the orientational energy density associated with the pattern-forming CLC state.
