Overview

Integration of encapsulation with flexible OLEDs demonstrates improved efficiency and stretchability in polymer blends, suggesting advancements in optoelectronic devices.

Key Points

  • The research aims to enhance the performance of flexible OLEDs by integrating TADF polymers with innovative encapsulation methods.
  • Developed dot‐coil copolymers incorporating SFX endcapping and synthesized reference copolymers without SFX.
  • Evaluated external quantum efficiency and stretchability in polyurethane blends.
  • Measured luminance and current efficiency in composite-based devices.
  • PCNSFX achieved an external quantum efficiency of 13.4% with 30% stretchability.
  • The composite-based devices exhibited a luminance of 4572 cd m − 2 and a current efficiency of 22.3 cd A − 1.
  • Performance improvements stemmed from reduced aggregation‐induced quenching and enhanced mechanical properties.
