摘要：

New structures for blue light emitting amorphous materials, based an an extended spiro-structural concept are reported. The chromophores are essentially based on p-oligophenyl chromophores, with further improved optical and morphological properties. The photoluminescence quantum efficiency of the blue emitter in amorphous solid state reach about 70%. New oxadiazole based electron transport materials are presented, where triptycenes have been used as new structural motif to increase the morphologic stability and preserve the electronic properties of the parent compound. Both, the emitting material and the electron transport materials can be processed into thin amorphous films with high morphologic stability by vapor deposition as well as by spin-coating from solutions in organic solvents.
