Stable luminescent diphenylamine biphenylmethyl radicals with α-type D₀ → D₁ transition and antiferromagnetic properties.

ABSTRACT: Organic luminescent radicals, with their open-shell electronic structure, exhibit appealing optoelectronic properties and hold promise for a wide range of potential applications. Although a few series of luminescent radicals have been reported, most feature D₀ → D₁ transitions dominated by HOMOβ-SOMOβ (β-type transitions). In contrast, luminescent radicals that exhibit SOMOα-LUMOα properties (α-type transitions) are much rarer. Here, we designed and synthesized two stable novel diphenylamine biphenylmethyl (BTM) luminescent radicals, both characterized by α-type D₀ → D₁ transitions, and simultaneously maintained the D-A˙ structure for the first time. Density functional theory (DFT) calculations confirmed that fine-tuning the energy levels of fron
