Research question

Design of new organic light emitting radicals for utilizing them in radical light emitting diodes with absolute internal quantum efficiency 100% by using modern quantum-chemical approaches including calculations of radiative doublet-doublet fluorescence, doublet-quartet phosphorescence and nonradiative doublet-doublet internal conversion and inter-system crossing pathways of excitation energy dissipation. To accomplish that the key important challenges will be addressed: i) how to make organic radicals as bright and stable as possible at the same time; ii) how to enhance the efficiency of radical-based OLEDs (practical recommendations); iii) how to make radicals phosphorescent.

Sustainability aspects

Current project close relates to the several WISE Sustainability Development Goals (SDGs) such as affordable materials able to be produced and recycled, enabling economic advancement (SDG 1), materials enabling good health and protection against hazardous compounds (SDG 3), green materials for efficient technology and infrastructure to harvest, transport, store, and convert energy (SDG 7) and resource-efficient use of materials for processes enabling an increased value of materials (SDG 8).
