Regiosymmetric Poly(dialkylphenylenedioxythiophene)s: Electron‐Rich, Stackable π‐Conjugated Nanoribbons

Abstract

Colored ribbons: The soluble, electron-rich conjugated title polymer (alkyl=dodecyl) with a regiosymmetric structure was synthesized by Grignard metathesis. The polymer displays strong thermochromism in solution. AFM images of spin-coated films show the formation of nanoribbons, and 2D-WAXS analysis reveals 2D order in the bulk material (see picture). The polymer is thus a promising candidate for device applications.
