Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, EarlyView.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.
