Abstract
The fabrication of single-carrier organic diodes from a series of sixteen molecular materials is reported. We experimentally demonstrate how the molecular structure affects the film morphology, and how the film morphology influences the diode performance. The compounds, with moderate molecular size and dendritic structures, are shown to be more favorable for good device performance than those small molecules with symmetry structures. The device turn-on voltage is found to be strongly dependent on the molecular first oxidation potentials. Independent of different anode materials, no obvious interfacial charge/dipole effects are observed in the devices. Our results may suggest that singlecarrier organic diode might offer a simple way for screeing appropriate molecular materials preferable for practical multilayer devices.
