A feasible acceptor–donor–donor′–donor–acceptor (A–D–D′–D–A) type hybridized local and charge-transfer emitter for efficient deep-blue electroluminescence

A feasible acceptor–donor–donor′–donor–acceptor architecture was introduced to engineer an effective and stable deep-blue HLCT emitter, achieving an EQE of 5.78% with color coordinates of (0.160, 0.054).
