Key Points

The study demonstrates that peripherally fused spiro structures enhance the efficiency of blue OLEDs.
Narrowband TADF emitters were designed to address aggregation, leading to improved performance.
Aggregation issues were linked to the planar structures typical of MR-TADF emitters.
This approach may transform the development of blue OLEDs by reducing spectral broadening.

Implication

Observational analysis of narrowband TADF emitters highlights their potential in blue OLEDs, suggesting reduced aggregation issues.

Abstract

To address the spectral broadening and red shift inherent in multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters, which are caused by aggregation due to their planar structures, we design a...
