Iridium and Platinum Complexes for Organic Light-Emitting Diodes and Circularly Polarized Luminescence
This community designs and synthesizes transition metal complexes and organic molecules that emit light, primarily for use in display technologies, optical sensing, and stereoscopic imaging.
The work centers on the synthesis of cyclometalated iridium and platinum complexes, alongside organic emitters based on thermally activated delayed fluorescence and multi-resonance structures. Recurring themes include the engineering of deep blue and near-infrared emission, the development of circularly polarized luminescence for 3D imaging, and the study of room-temperature phosphorescence. Methods frequently involve donor-acceptor ligand design, charge transfer optimization, and photophysical characterization to improve emission efficiency and color purity. Specific applications cited in the literature include ultrahigh-definition displays, flexible stereoscopic 3D imaging, and anticounterfeiting materials.
The largest share of this community's output is found in iridium research, accounting for 12.6% of all tracked iridium papers, and ruthenium research, representing 9.1% of that element's total. In absolute terms, the community contains 6,524 papers related to ruthenium and 5,289 related to iridium.
The community comprises 45,384 papers, publishing most frequently in Inorganic Chemistry, the Journal of the American Chemical Society, and Dalton Transactions.
Recent work continues to focus on narrowband emitters for pure-color OLEDs, including selenium-embedded hetero rings and diboraanthracene scaffolds, as well as the development of high-color-quality white organic light-emitting diodes and rigid ionic-bonding networks for room-temperature phosphorescence.
