Perspective on doublet electroluminescence from organic radicals
Abstract
The doublet emission from organic open-shell monoradicals is spin-allowed, enabling 100% internal quantum efficiency when electroexcitation occurs in organic light-emitting diodes. Research works on luminescent organic radicals have shown significant potential for high-efficiency electroluminescence, achieving device efficiencies comparable to those of close-shell emitters. This Perspective reviews recent advancements in spin-doublet organic monoradicals, highlighting molecular design principles, device optimizations, and potential futures.
