Electron transport in starburst phenylquinoxalines

Abstract

The electron transport properties of two soluble tris-phenylquinoxalines have been investigated by the time-of-flight technique. The electron mobilities for both compounds approach 10-4 cm2/V s at electric fields of 106 V/cm at room temperature. These are high values for isotropic electron transport materials suitable for use in organic light emitting diodes. © 1999 American Institute of Physics.
