Conjugated dendrimers for LEDs: Control of colour

The use of conjugated dendrimers as a novel molecular architecture for organic LEDs is investigated. Control of colour is demonstrated using materials based on a porphyrin, anthracene and distyrylbenzene core with stilbene dendrons. The resulting dendrimers are solution processible and give photoluminescence and electroluminescence in the red, green and blue regions of the spectrum.
