dc.description.abstractThe first examples of room temperature (r.t.) luminescent Co(III) complexes ( 1 and 2 ) are presented that exhibit intense ligand‐to‐metal and ligand‐to‐ligand charge transfer absorption in the low energy UV region (λabs ~ 360‐400 nm) and low‐negative quasi‐reversible reduction events (E1/2(red) = −0.58 V and −0.39 V vs. SCE for 1 and 2 , respectively). The blue emission of 1 and 2 at r.t. is due to the large bite angles and strong σ‐donation of the ligands, the combined effect of which helps to separate the emissive 3LMCT (triplet ligand‐to‐metal charge transfer) and the non‐emissive 3MC (triplet metal‐centered) states. 1 and 2 were found to be powerful photo‐oxidants (ECo(III)*/Co(II) = 2.26 V and 2.75 V vs. SCE of 1 and 2 , respectively) and were used as inexpensive photoredox catalysts for the regioselective mono(trifluoromethylation) of polycyclic aromatic hydrocarbons (PAHs) in good yields (~ 40‐58%).
