Abstract
None:
We unveiled a double interlocking strategy to construct a narrowband ultraviolet (UV) emitter based on indolo[3,2,1-jk]carbazole. The emitter exhibited pure UV emission (λem ∼ 398 nm) with a narrow FWHM of 24 nm. As an OLED emitter, it demonstrated an EQEmax of 4.2% and CIEy of 0.024. Used as a host for green PhOLEDs, it delivered EQEmax of 18.5% with an extremely low roll-off of 1% at 3000 cd m-2.
