Process for preparing pentacene derivatives

A process for preparing substituted pentacene compounds comprises the step of cyclizing substituted bis(benzyl)phthalic acids using an acid composition comprising trifluoromethanesulfonic acid, the substituted bis(benzyl)phthalic acids being represented by the following general formulas: wherein each R (that is, each of the groups R1 through R8) is independently an electron-donating group, a halogen atom, a hydrogen atom, or a combination thereof.

Substituted pentacene semiconductors

Substituted pentacene compounds comprise at least one substituent selected from the group consisting of electron-donating substituents, halogen substituents, and combinations thereof; the substituent(s) each being bonded to a carbon atom of a terminal ring of pentacene, and being the only substituent(s); with the proviso that when the compound has only two substituents, both of which are methyl or alkoxy, and one substituent is bonded to the number 2 carbon atom, the other substituent, if methyl, is bonded to the number 1, 3, 4, 8, or 11 carbon atom and, if alkoxy, is bonded to the number 1, 3, 4, 8, 9, or 11 carbon atom; and with the further proviso that when the compound has only four substituents, all of which are alkoxy, the substituents are bonded to the numbers 2, 3, 9, and 10 carbon atoms.
