Abstract
A novel soluble pentacene (C22H14) precursor 6,13-dihydro-6,13-methanopentacene-15-one, a method for its production and intermediates therefor as well as pentacene films and coated surfaces. Thermolysis of the precursor at 150° C. to 350° C. induces an expulsion of carbon monoxide to generate pentacene in high yield. The high solubility of the precursor compound, as well as its production of non-contaminated pentacene, makes it an excellent material in the application of organic thin film transistors on surfaces.
