Summary
Stable neutral π-radicals can utilise up to 100% of excitons as doublet emission in organic light-emitting diodes (OLEDs), thus circumventing the limitations of traditional fluorescent (singlet) and phosphorescent (triplet) emitters. Our aim is to develop polymer radicals as a new class of highly luminescent emitters by chemically coupling stable radical molecules into suited polymer backbones. This will interconnect the benefits of low-cost solution-based processing of conjugated polymers and the attainable high efficiency of doublet emission from π-radicals. Novel polymers will be synthesized and scrutinized using a range of state-of-the-art spectroscopic techniques. The most promising polymers will be selected for OLEDs fabrication using solution-based methods. Polymer radicals exhibit simultaneously optical, electronic and magnetic properties. This will open new possibilities not only for OLEDs but also for other fields, such as photovoltaics, polymer magnetics, lightweight batteries and supercapacitors, spintronics and antistatic coatings for consumer electronics.
