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.
取代的五环蒽化合物包括至少一种取代基,所选取代基来自包括供电子取代基、卤素取代基和它们的组合的群组;每个取代基与五环蒽的一个端环的碳原子键合,并且是唯一的取代基;但是,如果化合物只有两个取代基,两者都是甲基或烷氧基,并且一个取代基键合到第2碳原子,则另一个取代基如果是甲基,则键合到第1、3、4、8或11碳原子,如果是烷氧基,则键合到第1、3、4、8、9或11碳原子;而且如果化合物只有四个取代基,全部是烷氧基,则这些取代基键合到第2、3、9和10碳原子。
