Instead of manufacturing long chain, multi-functional group, electroluminescent polymers with a complex, slow and expensive synthesis path, we will study the feasibility of using accurate formulations of a number of emitters to tailor the emission spectra. Should this prove feasible, then it would be possible to 'dial up' a particular emission spectrum by rapidly formulating known electroluminescent polymer or small molecule constituents. This will allow rapid prototyping of organic light emitting devices for a number of different niches, including but not limited to, medical devices for phototherapy.
