Rubrene

Rubrene, molecular semiconductor with high charge mobility

Applications in organic electronics (OLEDs and OFETs)

Rubrene, a molecule with a tetracene backbone and four appended phenyl rings, is one of the most studied molecular semiconductors due to its high charge mobility. Notably, room-temperature hole mobilities of the order of 20-40 cm²V^-1s^-1 have been measured for rubrene in single-crystal organic field-effect transistors (SC-OFET) [1]. It is widely used in organic electronics, especially organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs).
