Application

Pentacene, a compound comprising five linearly-fused benzene rings, is purified by sublimation and serves as a crucial material in the field of electronics. Its flat molecular structure has made it a subject of extensive study as a p-type semiconductor in organic field-effect transistors, where it demonstrates impressive carrier mobilities of about 1 cm²/Vs in the plane parallel to the substrate. Beyond transistors, pentacene's substantial carrier mobilities facilitate its use in heterojunction solar cells, where it pairs with C60 to achieve power conversion efficiencies exceeding 2.7%. Additionally, its properties make it suitable for light-emitting diode applications, highlighting its versatility and importance in advanced electronic and photovoltaic systems.
