A double interlocking strategy for narrowband ultra-violet emitters (CIE<sub><i>y</i></sub> ≈ 0.029) with dual functionality for efficient OLEDs
We unveiled a double interlocking strategy to construct a narrowband ultraviolet (UV) emitter based on indolo[3,2,1-<i>jk</i>]carbazole. The emitter exhibited pure UV emission (<i>λ</i><sub>em</sub> ∼ 398 nm) with a narrow FWHM of 24 nm. As an OLED emitter, it demonstrated an EQE<sub>max</sub> of 4.2% and CIE<sub><i>y</i></sub> of 0.024. Used as a host for green PhOLEDs, it delivered EQE<sub>max</sub> of 18.5% with an extremely low roll-off of 1% at 3000 cd m<sup>-2</sup>.
