The simplest structure of a stable radical showing high fluorescence efficiency in solution: benzene donors with triarylmethyl radicals

This is the authors' abstract. We don't add key points for this paper.

By adding mesityl donors to a diphenylpyridyl radical acceptor, a highly luminescent stable radical was prepared in three steps from commercially available reagents. The photoluminescence quantum yield was as much as 69% in chloroform.
