Achieving Record External Quantum Efficiency of 11.5 % in Solution‐Processable Deep‐Blue Organic Light‐Emitting Diodes Utilizing Hot Exciton Mechanism

High performance solution‐processable deep‐blue emitters with a Commission International de l′Eclairage (CIE) coordinate of CIEy≤0.08 are highly desired in ultrahigh‐definition display. Although, deep‐blue materials with hybridized local and charge‐transfer (HLCT) excited‐state feature are promising...
