Key Points

Enhanced efficiency in blue electroluminescence demonstrates improved carrier transport balance in the materials used.
The study addresses the contradiction between wide bandgap and carrier injection, achieving negligible efficiency roll-off.
The approach involves a D-π-A type molecular design that optimizes carrier dynamics and electronic interactions.
Findings suggest this synergy between carrier transport and excited states could advance non-doped organic emitters.
