  • SYNTHESIS AND APPLICATIONS OF SOLUBLE PENTACENE PRECURSORS AND RELATED COMPOUNDS
    Publication number: 20090226634
    Abstract: Methods for synthesizing 1,4-(ketone or ketal) bridged and/or 5,14-(ketone or ketal) bridged hydropentacenes useful as soluble precursors for formation of pentacene or substituted (e.g., halo) pentacenes; precursor compounds formed thereby; methods for preparing form the precursor compounds conductive thin films comprising pentacene or a substituted pentacene, and articles including such thin films are described. Also described are tetracene and anthracene derivatives which should also be useful in the formation of conductive thin films, among other uses.
