Benzimidazoline radical dimers that can be handled in air but that function as powerful reductants are reported and evaluated as n‐dopants by solution‐ and vacuum processing. In several host materials, one of these dimers is found to have a more‐consistent doping effect than a hydride‐donor dopant analog. Notably, a record high room‐temperature conductivity of 12.0 S cm −1 is obtained for doped C 60 .
