Hoichang Yang, John E. Anthony, Chan Eon Park, and co-workers describe a new chemically linked polymer-coupling method for the surface modification of oxide dielectrics that enables multipurpose organic electronic applications. Ultrathin polymer layers are chemically coupled on oxide dielectrics with chlorosilane-terminated polystyrene. The polystyrene brush layer is physicochemically stable and provides a hydrophobic and smooth surface to induce highly ordered crystalline structures of vacuum- and solutionprocessable organic semiconductors. on page 2198
