“Four-in-One” Strategy to Functionalize a Multiple Resonance Skeleton for Narrowband Ultrapure Green Emitters with Circularly Polarized Luminescence
Novel chiral emitters are constructed using a "four-in-one" strategy through attachment of an octahydro-binaphthol unit onto a boron/nitrogen multiple resonance skeleton. They manifest ultrapure green emission peaking at 511 nm, a full width at half maximum of 22 nm, a Commission Internationale de l'Eclairage <i>y</i> coordinate of 0.73, a small Δ<i>E</i><sub>ST</sub> of 0.05 eV, a high quantum yield of 98.46%, and circularly polarized photoluminescence. The organic light-emitting diodes exhibit excellent performances with CIE coordinates of (0.21, 0.73), consistent with the National Television System Committee green standard.
