Organic light emitting diodes (OLEDs)

OLEDs are an exciting new technology for flat panel displays that may even lead to roll up television screens. Light-emitting dendrimers consist of surface groups, dendrons (branched units) and cores. Dendrimers have a number of potential advantages over existing OLED materials (small molecules and polymers) including a modular approach to synthesis leading to dendrimer libraries and disconnection of the electronic and processing properties. Figure 1 illustrates an example of a family of highly efficient phosphorescent dendrimers that are currently exciting international academic and industrial interest.

Renewable and green energy has been highlighted as an important target for Australian science. Our strategy has been drawn from nature where porphyrin arrays are used for light collection in photosynthesis. We have molecularly engineered the porphyrin structure to enable the development of macromolecular structures based on porphyrin arrays.
