Abstract

Thermally Activated Delayed Fluorescence (TADF) compounds wherein two aromatic heterocyclic moieties are provided as acceptor groups, spaced apart from two donor moieties by an aromatic spacer ring, are described. Charged organic TADF species having a similar structure are also described. The TADF compounds and charged organic TADF species may be employed as emitter material in light emitting devices such as OLEDs and LEECs. Also described TADF compounds wherein at least one donor moiety is substituted by at least one substituent that is a phosphine oxide or a phosphine sulphide.
