Donor-radical acceptor systems have recently attracted much attention as efficient doublet emitters that offers significant advantages for applications such as OLEDs. We employed an alkylbenzene (mesityl group) as the simplest...

The 4% fluorescence quantum yield of F2PyBTM radical in dichloromethane was enhanced up to 36% by coordination to AuI with N-heterocyclic carbene ligand.

Quadruple addition of phenyl groups to a diphenylpyridylmethane skeleton was achieved. The derived (3,5-difluoro-4-pyridyl)bis(2,6-dichloro-3,4-diphenylphenyl)methyl radical (Ph4-F2PyBTM) displayed superior luminescent properties to the previously reported organic diphenylpyridylmethyl radicals in various organic...
