In the realm of copper (I) photocatalysts, oxidative quenching cycles through metal-to-ligand charge transfer (MLCT) processes are more prevalent than reductive quenching cycles. This underscores the propensity of copper (I) photocatalysts to serve as superior reductants rather than oxidants. Conversely, exploration of photoexcited copper (II) complexes as oxidants via outer sphere electron transfer remains limited due to the low oxidation potential associated with copper (II) complexes (Ered = + 0.50 V vs SCE). Nevertheless, a viable strategy for leveraging copper (II) as a photoredox catalyst involves harnessing ligandinduced net homolysis (LIH) initiated by Ligand-to-Metal Charge Transfer (LMCT) (Figure ). LMCT entails the excitation of an electron from a fully occupied ligand orbital to a singly occupied d orbital of a copper (II) complex (Figure ). This excitation can result in two distinct pathways: (i) predominant non-radiative relaxation back to the electronic ground state, either directly or cascading through lower-lying ligand field excited states (in less than 1ps), or (ii) initiation of an electron transfer, facilitating "net homolytic cleavage" of the Cu(II)-(X) bond. This process generates Cu(I) and X radical species, serving as an onset for further chemical reactions. Consequently, the overall process equates to a one-electron oxidation of the X anion. This methodology offers high chemo-selectivity, as precoordination of Cu(II)-X is a prerequisite, ensuring precise control over reaction pathways.
