Key Points

The aim is to investigate how different dibenzofuran-based hosts affect the stability of blue TADF-OLEDs under electrical stress.
Conducted a structure-property analysis of four dibenzofuran-biphenyl derivatives.
Assessed the response of hosts to electrical stress.
Evaluated the triplet energy levels of the hosts.
Identified a correlation between host structure and operational stability.
Demonstrated that higher triplet energy contributes to improved performance under electrical stress.

Implication

Structure-property study demonstrates improved stability in blue TADF-OLEDs via host modifications, highlighting implications for future designs.

Abstract

Stability remains the principal bottleneck for blue TADF-OLEDs, and it is strongly affected by the host response to electrical stress. Here we report a structure-property study of four hightriplet-energy dibenzofuran-biphenyl...
