Abstract: A composition for forming a semiconducting device includes an organic semiconducting material, an agent capable of inhibiting and/or preventing dewetting, and an additional substance, wherein the additional substance is provided in an amount capable of preventing initial crystallization of the composition and reducing the melting point or glass transition temperature of the composition below the melting point or glass transition temperature of the organic semiconducting material. The additional substance may be naphthalene, phenylnaphthalene, anthrance, or diphenylanthrance.

Abstract: The present invention provides a method of forming a semiconducting device comprising an organic semiconducting material, which method comprises: heating a composition comprising the organic semiconducting material to a temperature at or above the melting point or glass transition temperature of the composition to form a melt; cooling the melt to a temperature below the melting point or glass transition temperature of the composition; and wherein a first substance or object capable of inhibiting and/or preventing dewetting is adjacent the composition before or during heating, or the composition further comprises an agent capable of inhibiting and/or preventing dewetting.

Abstract: A method is provided for microstructuring polymer-supported materials. Also provided are microstructured objects obtained with this method. The microstructured objects are suitable for use, among other things, as light polarizers, transflectors, microelectrode arrays, and liquid-crystal alignment layers.

Abstract: A method for forming an organic or partly organic switching device, comprising: depositing layers of conducting, semiconducting and/or insulating layers by solution processing and direct printing; defining microgrooves in the multilayer structure by solid state embossing; and forming a switching device inside the microgroove.

Abstract: A new class of organic-inorganic materials for thin film semiconducting devices that exhibit good stability in air and water, as well as a new purification technique for thin film semiconducting devices that contain impurities, such as ionic species.

Abstract: The present invention provides polarizing devices and illumination devices that include the polarizing devices. The polarizing devices and illumination devices can be advantageously used in a wide variety of applications, such as in liquid crystal displays. Polarizing devices provided by the present invention include those having an isotropic waveguiding layer with a refractive index ni and an anisotropic separating layer having an anisotropic region with principal refractive indices nx and ny, wherein nx>ny and wherein ni is substantially smaller than nx and substantially larger than ny. An example of a further polarizing device provided by the present invention is one having a waveguiding layer and a separating layer, wherein the separating layer includes a form birefringent region.
