Soluble 2,6-Bis(4-pentylphenylethynyl)anthracene as a High Hole Mobility Semiconductor for Organic Field-effect Transistors

The balance between good solubility and high crystallinity is an advantageous characteristic of 2,6-bis(4-pentylphenylethynyl)anthracene (1). Organic field-effect transistors featuring either a vacuum-deposited film or a simple drop-cast film of 1 both showed high hole mobilities of 0.94 and 0.63 cm2 V−1 s−1, respectively.
