摘要:A single-step method of making tetradentate platinum complexes is disclosed. The method advantageously allows the formation of a platinum complex in a single step, even with sterically hindered ligands, without the use of highly reactive intermediates. The compounds made by the disclosed method are useful in OLED applications.

摘要:The present inventive concept relates to an in situ core/shell perovskite nanocrystal film formed by an in situ nanocrystal synthesis process, a method for producing the same, and a light emitting device comprising the same as a light-emitting layer. The in situ core/shell perovskite nanocrystal film formed by the in situ nanocrystal synthesis process according to the present inventive concept exhibits a strong charge confinement effect by nanocrystal formation, and can simultaneously greatly improve the luminescence efficiency and lifetime by maintaining the fast charge transport capability of polycrystalline perovskite.

摘要:A high-purity organometallic iridium complex is provided. The organometallic iridium complex includes iridium and a plurality of ligands cyclometallated to the iridium. Each of the plurality of ligands includes a heteroaromatic ring having a coordinatable nitrogen atom. In LC analysis of the organometallic iridium complex, an impurity which has a monochlorinated ligand among the plurality of ligands is 0.1% or less by quantitating using peak area count with a PDA detector.

标 题 :Derivate of quinoxaline with thermally activated delayed fluorescence

权利人:UNIV GDANSKI
摘要:The invention relates to the triarylamine derivatives of quinoxaline with thermally activated delayed fluorescence (TADF) bearing heavy atoms and methods of their synthesis. The emitters are characterized by spectral and photophysical properties with improved TADF parameters as compared to their analogues reported before. The disclosed emitters can convert triplet excitons into singlet ones faster and with higher efficiency. The emitters cover orange, red, and/or near infrared (NIR) spectral ranges. Furthermore, the mixtures of new emitters with fluorescent dopants exhibit narrowband NIR emission preserving fast triplet-singlet exciton conversion.The invention concerns functional organic materials which exhibit TADF and can be potentially used for the electroluminescence applications, e.g. in organic light emitting diodes (OLED), and/or applications of materials with long-lived excited states, e.g. photosensibilization, photocatalysis, and/or other fields where excited triplet states or excitons play important role.
