Application

Pentacene (purified by sublimation) is a polycyclic aromatic compound characterized by its structure of five linearly-fused benzene rings. Its unique molecular arrangement allows it to function effectively as a p-type semiconductor in organic field-effect transistors, where it demonstrates significant carrier mobilities of approximately 1 cm²/V·s. This high mobility is particularly advantageous in applications where charge transport parallel to the substrate is critical. Moreover, pentacene is utilized in the development of heterojunction solar cells alongside C60, achieving a power conversion efficiency exceeding 2.7%. Additionally, its properties make it suitable for use in devices designed for light-emitting diode applications.
