Project R-15242

Innovative all-organic chiral emitters for circularly polarized organic light-emitting diodes (Research)

Over the last decade, electroluminescence from organic chromophores has evolved into a flourishingindustry. Strategic materials and device research efforts have been key to this commercial success. Most recentendeavors aim at triplet leveraging without the use of (toxic) heavy metals to afford more efficient and sustainableorganic light-emitting diodes (OLEDs). When applying chiral organic emitters, circularly polarized (CP)electroluminescence can be achieved, with exciting prospects for power-efficient OLED screens, 3D displays, opticaldata storage, and optical spintronics. However, this field is still in its infancy and the development of efficient all-organic chiral emitters and devices thereof comes with considerable scientific challenges. In this project, thesechallenges are tackled by judicious - computationally guided - design and synthesis of innovative chiral chromophoreswith enhanced luminescence dissymmetry factors. All novel fluorophores will be thoroughly characterized from astructural and photophysical/chiroptical point of view and then implemented in state-of-the-art CP-OLEDs to afforddetailed structure-property relations.
