title = "Achieving High-Performance Solution-Processed Deep-Red/Near-Infrared Organic Light-Emitting Diodes with a Phenanthroline-Based and Wedge-Shaped Fluorophore",
abstract = "A phenanthroline-based donor–acceptor type fluorophore is designed and synthesized, and its thermal, photophysical, and electrochemical characteristics are investigated. This fluorophore displays a strong deep-red/near-infrared (DR/NIR) emission with the photoluminescence quantum yield of 74.8% in nonpolar n-hexane solvent and 4.5% in polar chloroform solvent, as well as 1.26% in neat film and 18.4% in 5 wt% doped poly(methyl methacrylate) film. DR/NIR devices are fabricated, with emission peaks at 670–696 nm and external quantum efficiencies of 3.18–1.43% at different doping concentrations.",
