标 题 :Derivate of quinoxaline with thermally activated delayed fluorescence

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.
