Organic Molecular Beam Deposition of l,3,5(TRIS(6,7-DIMETHYL-3-PHENYL)QUINOXALINE-2-YL)BENZENE

Introduction of molecular order into the active layer of an organic light-emitting diode (OLED) is a promising approach to control luminescence as well as charge transport properties. For instance charge carrier transport is very sensitive to the degree of molecular order, packing and orientation, and mobilities can be considerably enhanced by proper molecular engineering. Organic molecular beam deposition (OMBD) has been shown to be a very powerful tool to build structures with well-defined molecular order if the deposition conditions are properly chosen. Especially the choice of the substrate, substrate temperature and deposition rate is crucial...
