Crystalline Colloidal Arrays Composed of Poly(3,4‐ethylenedioxythiophene)‐Coated Polystyrene Particles with a Stop Band in the Visible Regime

Abstract

Monodisperse polystyrene particles with a diameter of ca. 100 nm have been coated with 8 nm shells of poly(3,4‐ethylenedioxythiophene) (PEDOT) and self‐assembled into crystalline colloidal arrays (see Figure) with an observed stop band in the visible regime. These materials could be used in developing photonic crystals with frequency‐ and dopant‐dependent optical properties .
