Abstract: Acene-thiophene copolymers with attached silylethynyl groups are provided that can be used in electronic devices. The copolymers are often soluble in common organic solvents and can be part of a coating composition.

Abstract: Electronic devices that include an acene-thiophene copolymer and methods of making such electronic devices are described. The acene-thiophene copolymer can be used, for example, in a semiconductor layer or in a layer positioned between a first electrode and a second electrode.

Abstract: A coated article having a substrate coated with a layer of acicular silica particles is provided. The coating is substantially uniform in thickness, durably adheres to the substrate, and provides antireflection and or hydrophilic surface properties to the substrate.

Abstract: Acene-thiophene copolymers are provided that can be used as semiconductor materials in electronic devices. The acene-thiophene copolymers are of Formula I. In Formula I, Ac is a radical of an acene having 2 to 5 fused aromatic rings. The acene can be unsubstituted or substituted with a substituent selected from an alkyl, alkoxy, thioalkyl, aryl, aralkyl, halo, haloalkyl, hydroxyalkyl, heteroalkyl, alkenyl, or combinations thereof. Divalent group Q is selected from Formula III where each R1 and R2 group is independently selected from hydrogen, alkyl, alkoxy, thioalkyl, aryl, aralkyl, halo, haloalkyl, hydroxyalkyl, heteroalkyl, alkenyl, or combinations thereof. The subscript n in Formula I is an integer equal to at least 4. The asterisks in Formula I indicate the location of attachment to another group such as another repeat unit of formula —Ac-Q-.

Abstract: Electronic devices that include an acene-thiophene copolymer and methods of making such electronic devices are described. More specifically, the acene-thiophene copolymer has attached silylethynyl groups. The copolymer can be used, for example, in a semiconductor layer or in a layer positioned between a first electrode and a second electrode.

Abstract: The present invention introduces a novel route toward microstructural orientation into organic films, using multiple hydrogen-bonding to self-assemble chromophore molecules into electro-optic films in a net polar orientation. High-quality, thick films (up to micrometers) with molecular net dipole orientations can be fabricated under vacuum in hours. The film microstructure is intrinsically acentric; and the orientation is robust.
