European Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.A range of synthetic methods for photophysically attractive stable luminescent diradicals have been developed, enabling the preparation of diverse derivatives. Direct substitution of the tris(2,4,6‐trichlorophenyl)methyl radical introduces donor groups to afford acceptor–donor–acceptor luminescent diradicals, while halogenated triarylmethanes are ...
