In recent years, due to its high hole-mobility, high on/off current ratio and low threshold voltage, pentacene and its derivatives have found increasing application in the fabrication of light-emitting diodes, field-effect transistors and photovoltaic cells. It has also emerged as an alternative to silicon due to its similar performance to inorganic semiconductors. Pentacene cannot be isolated from the petroleum fractions like other acenes such as anthracene or tetracene, and therefore it needs to be chemically synthesized. The first successful synthesis of pentacene was reported in early 19th century where pentacene was obtained via dehydrogenation of 6,14-dihydropentacene. Since then a number of methods have been reported for the synthesis of pentacene. This review describes various strategies used for the synthesis of pentacene and its derivatives reported since 2005.

近年来，并五苯及其衍生物由于其高的空穴迁移率，高的开/关电流比和低的阈值电压而在发光二极管，场效应晶体管和光伏电池的制造中得到越来越多的应用。由于其与无机半导体相似的性能，它也已成为硅的替代品。并五苯不能像其他并苯如蒽或并四苯那样从石油馏分中分离出来，因此需要化学合成。并五苯的第一个成功合成方法是在19世纪初报道的，其中并五苯是通过6,14-二氢并五苯脱氢制得的。从那时起，已经报道了许多并五苯的合成方法。
