Summary on Grant Application Form |
|
The project concerns the design and development of a new class of carbazole main chain conjugated polymers and investigation of their photophysical and electroluminescent properties in the area of fight emitting diodes. The polymers are designed in such a way as to have wide bandgaps, low ionisation potentials and high fluorescence quantum yields. The materials will be studied in LED devices both in their pristine form in order to develop highly electroluminescent blue emitting materials as well as hosts to selected fluorophore guests with lower energy bandgaps for emission in the green and red part of the electromagnetic spectrum. Different guests will be investigated in the project including phosphorescent dyes that have the potential to lead to electrophosphorescence upon the use of both singlet and triplet excitons generated on polymer chains. Selected rare earth chelate complexes which, have the benefit of producing light with narrow spectral emission lines, will also be studied as guests in the new polymers. Other fluorescent dyes such as Coumarin 6 and Nile red will also be studied as guests in the new polymers, both to complete the visible spectrum and to allow a direct comparison of their performance with that of the phosphorescent dyes used.
