Co(acacen)(Im)2 (1) adsorbs to the PbS QD surface and PET occurs from the PbS QD to 1, increasing propensity toward axial ligand dissociation (1*). Oxidation back to Co(III) provides open coordination sites in the axial positions for the incoming ligand – here, 4MeIm – to form a mixture of three species – 1, 2, and 3 in relative abundances of 25%, 50%, and 25%, respectively.
