Abstract

Organic LEDs based on dendrimer materials are reported (see the figure for an example; a dot represents phenylene). Single-organic-layer devices have been produced using structurally welldefined dendritic modules. Although the efficiency of the devices is still low, this work provides a basis for a systematic strategy for tuning the properties of the active layers of organic LEDs.
