Iridium and Platinum Complexes for Organic Light-Emitting Diodes
This community designs and synthesizes luminescent metal complexes and organic molecules to serve as light-emitting materials in organic light-emitting diodes (OLEDs).
The work centers on the synthesis of cyclometalated iridium(III) and platinum(II) complexes, as well as organic emitters based on thermally activated delayed fluorescence (TADF) and multi-resonance mechanisms. Key applications include deep-blue, green, and red OLEDs for high-definition displays, with significant focus on improving color purity, efficiency, and circularly polarized luminescence. The research involves detailed photophysical characterization, ligand engineering, and the study of charge transfer states to optimize emission properties for display technologies.
The largest share of the community's output is found in ruthenium research, accounting for 8.3% of all ruthenium research, and 6,333 papers here. Iridium research also features prominently, representing 12.2% of all iridium research, and 5,166 papers here.
The community comprises 32,437 papers, publishing most frequently in Inorganic Chemistry, Journal of the American Chemical Society, and Dalton Transactions.
Recent work continues to focus on developing narrowband blue and green emitters for OLEDs, including selenium-embedded hetero rings and chiral materials for circularly polarized light, as well as investigating spin-state considerations for metal-centered photoredox catalysis.
