Vorschrift

In summary, a new stable and soluble pentacene precursor 2 was synthesized in 40% yield from the cycloaddition of a furan derivative 3 and a benzonorbornadiene 4. Compound 2 releases a unit of CO upon heating at 128° C. or by irradiation with UV light (366 nm) to produce pentacene in nearly quantitative yield. Thin films of pentacene were prepared by spin-coating followed by thermal annealing, and found to display typical FET characteristics.
