Design, synthesis, and properties of new derivatives of pentacene.
Stable, soluble ethynylated derivatives of pentacene (9a-c) were synthesized, and the ethynyl moieties on the terminal rings were used to tune the electronic properties of these compounds. Their oxidation potentials are higher and their reduction potentials are lower than those of pentacene. The HOMO-LUMO gaps are among the lowest reported for pentacene derivatives.
