Organic Delayed Fluorescence Compounds and Electroluminescent Elements in Organic Light Emitting Diodes
Invention type: Technology
/
Case number: #17591J
A chemical compound is provided having a structure that includes at least one donor moiety covalently bonded to at least one acceptor moiety. For example, the compound may include an indolocarbazole moiety covalently bonded to at least one furylpyridine moiety. The compound may exhibit thermally activated delayed fluorescence and an accompanying ΔEST of no greater than about 0.25 eV. The compound finds use in OLED display technology.
