Application

This dihydrophenazine-based organic photoredox catalyst (in addition to the dihydrophenazine catalyst 901111) 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)
