3,7-Di(4-biphenyl) 1-naphthalene-10-phenoxazine >=97%

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.
