Abstract

ABSTRACT

In this study, we demonstrate intrinsically stretchable green phosphorescent light‐emitting diodes (IS‐PhOLEDs) utilizing small molecules, achieved through a mechanically compliant emissive layer. This layer is engineered by blending an elastomeric polymer with a nanocomposite host–dopant system of small molecules. Notably, the light‐emitting layer preserves equidistant under 30% applied strain, ensuring stable operation of IS‐PhOLEDs during deformation. The resulting IS‐PhOLEDs exhibit a 6.0 turn‐on voltage and achieve a maximum current efficiency and luminance of 15.12 cd A
−1
and 14,881 cd m
−2
. This device maintains consistent brightness without degradation, even when subjected to 30% mechanical strain.
