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.
取代的五环并芴化合物包括至少一种取代基,所述取代基选择自电子供体取代基、卤素取代基和它们的组合;每个取代基都与五环并芴的一个端环的碳原子键合,并且是唯一的取代基;但是,当该化合物只有两个取代基时,两个取代基都是甲基或烷氧基,一个取代基键合到2号碳原子,另一个取代基(如果是甲基)键合到1号、3号、4号、8号或11号碳原子,如果是烷氧基,则键合到1号、3号、4号、8号、9号或11号碳原子;并且进一步规定,当该化合物只有四个取代基时,所有取代基都是烷氧基,这些取代基键合到2号、3号、9号和10号碳原子。
