Abstract:
Disclosed are organic-inorganic hybrid self-assembled multilayers that can be used as electrically insulating (or dielectric) materials. These multilayers generally include an inorganic primer layer and one or more bilayers deposited thereon. Each bilayer includes a chromophore or “π-polarizable” layer and an inorganic capping layer composed of zirconia. Because of the regularity of the bilayer structure and the aligned orientation of the chromophore resulting from the self-assembly process, the present multilayers have applications in electronic devices such as thin film transistors, as well as in nonlinear optics and nonvolatile memories.
Abstract:
Disclosed are new organic semiconductor materials prepared from polymers based on N-alkyl-2,2′-bithiophene-3,3′-dicarboximide (BTI) repeating units. Such polymers can exhibit desirable electronic properties and can possess processing advantages including solution-processability and/or good stability at ambient conditions.
Abstract:
Disclosed are molecular and polymeric compounds having desirable properties as semiconducting materials. Such compounds can exhibit desirable electronic properties and possess processing advantages including solution-processability and/or good stability. Organic transistor and photovoltaic devices incorporating the present compounds as the active layer exhibit good device performance.

Abstract:
Disclosed are metal oxide-polymer composites having a substrate comprising a metal oxide component, an aluminum oxide component, and a metallocene olefin polymerization catalyst component coupled to the substrate. The compositions can be used as thin films in an insulator device. Also disclosed is a method of preparing such compositions.
