Summary on Grant Application Form |
|
It has been clearly demonstrated that Linear conjugated (co) polymers can be used as the light emitting layers in light emitting diodes and it is expected that these materials will play an important role in the displays market and wealth creation. However, to reach their full potential a number of materials problems need to be overcome including control of emission colour (particularly blue), simultaneous optimisation of efficiency and processing properties, and device lifetime. This proposal seeks to address these problems by the development of dendrimers: it describes the synthetic routes to dendrimers, characterisation of these novel compounds , and device fabrication. The dendrimers to be prepared will be based on arylenevinylenes and either be fully conjugated or have conjugated chromophores linked by non-conjugated sequences. The electronic properties of the dendrimers will be controlled by the chromophore conjugation length and substituent pattern, and the chromophore position with the dendrimer. The processing properties of the dendrimers will be controlled by the surface groups independently of the chromophores. The proposal divides into three sections; first the synthesis of the dendrimers; second the characterisation of their physical, electronic and processing properties; and finally, device fabrication and testing.
