are as defined herein. Compounds containing a moiety of Formula I are useful in a wide variety of applications including, but not limited to, as photocatalysts, use in OLEDs, in electronic components, etc. As an organic-based photocatalysts, compounds containing a moiety of Formula I are activated by a relatively low energy electromagnetic wavelength, e.g., wavelength of 600 nm or greater. Furthermore, compounds of the invention can be used as both photoreduction catalysts and photooxidation catalysts.
series of heteroleptic [Cu(phenantroline)(bisisonitrile)]+-complexes was synthesized, and their structural, spectroscopic, and electrochemical properties were investigated. The new copper(I) complexes were employed as photoredox-catalysts in the visible-light-mediated atom transfer radical addition (ATRA). Especially, [Cu(dpp)(binc)]BF4 (6a-BF4)(dpp = 2,9-diphenyl-1,10-phenanthroline; binc = bis(2-isocyanophenyl)

complex [Cu(dmp)2Cl]Cl is introduced to visible‐light photocatalysis, being efficient but considerable more cost‐effective compared to previously established CuI photocatalysts within a broad scope of different reactions. Furthermore, this study provides UV/Vis evidence for the visible light activation of CuII complexes, suggesting an LMCT process resulting in the visible light homolysis of CuII‐Cl to give

m (nPr-DMQA+) tetrafluoroborate) has been used as an organic photoredox catalyst for photoreductions and photooxidations in the presence of red light (λmax = 640 nm). It has catalyzed red-light-mediated dual transition-metal/photoredox-catalyzed C-H arylation and intermolecular atom transfer radical addition through oxidative quenching. Moreover, its potential in photooxidation catalysis has also been
