Application

This phenoxazine-based organic photoredox catalyst (in addition to the dihydrophenazine catalyst 901112) was designed to be a strong excited-state reductant and possesses advanced photophysical and electrochemical properties, enabling it to serve as a sustainable replacement for ruthenium- or iridium-based photoredox catalysts. For example, dihydrophenazine and phenoxazine derivatives were demonstrated to replace ruthenium or iridium complexes in the application of photoredox-catalyzed atom transfer radical polymerization (ATRP) for controlled polymer synthesis and small molecule transformations such as trifluoromethylation, atom transfer radical addition, and dual Nickel/photoredox catalyzed C-N and C-S cross-couplings. Dihydrophenazine- and phenoxazine-based organic photoredox catalysts were introduced in collaboration with the Miyake Research Group.

Product can be used with our line of photoreactors: Including Penn PhD (Z744035) & SynLED 2.0 (Z744080)

Photoredox catalysis is a versatile approach for the construction of challenging covalent bonds under mild reaction conditions, commonly using photoredox catalysts (PCs) derived from precious metals. As such, there is need to develop organic analogues as sustainable replacements. Although several

N-Aryl phenoxazines have been synthesized and introduced as strongly reducing metal-free photoredox catalysts in organocatalyzed atom transfer radical polymerization for the synthesis of well-defined polymers. Experiments confirmed quantum chemical predictions that, like their dihydrophenazine analogs, the photoexcited states of phenoxazine

Photoexcited intramolecular charge transfer (CT) states in N,N-diaryl dihydrophenazine photoredox catalysts are accessed through catalyst design and investigated through combined experimental studies and density functional theory (DFT) calculations. These CT states are reminiscent of the metal to ligand charge transfer

Articles

Photoredox catalysis is a powerful synthetic methodology to form challenging covalent bonds using light irradiation. It is effective for light-driven polymer and small molecule synthesis.
