Iridium(<scp>iii</scp>) phosphors with rigid fused-heterocyclic chelating architectures for efficient deep-red/near-infrared emissions in polymer light-emitting diodes

Abstract

Highly efficient deep-red/near-infrared emissions with maximum EQEs of 7.04% and 4.14%, respectively, are realized for Ir(<sc>iii</sc>) complexes by designing rigid fused-heterocyclic ligands.
