Intrinsically Stretchable Ortho‐Steric Engineered MR‐TADF Polymers With in Situ Hypercrosslinking for Narrowband Deep‐Blue OLEDs
Intrinsically stretchable organic light‐emitting diodes (OLEDs) are the core building blocks for next‐generation wearable electronics and flexible ultra‐high‐definition (UHD) displays. However, intrinsically stretchable deep‐blue polymers with narrowband emission and ultra‐high color purity (CIE y < 0.1) have remaine...
