ABSTRACT:
The present invention is directed to multi-layer organic devices having improved stability, wherein at least one layer of the device comprises a host material that is morphologically unstable and a dopant material that provides improved morphological properties to the layer. The layer may be incorporated into, for example, OLEDs, organic phototransistors, organic photovoltaic cells, and organic photodetectors.
