title: Monolayer transistor using a highly ordered conjugated polymer as the channel.
abstract: Field-effect transistor structures based on polydiacetylene (PDA) derivatives have been fabricated. Monolayer channels of UV polymerized pentacosa-10,12-diynoic ethanolamide exhibit modulation of source-drain current on application of a gating voltage. Comparison of the two-dimensional crystal morphology of this material with several closely related derivatives that show no gating suggests that a high degree of alignment and order in the polymer chains is necessary for the observed transistor action.
