Phenox O-PC™ A0208
- Chemical Family
- Oxazines
Phenoxazine photocatalysts A0208 (Phenox O-PC™) are some of the strongest reducing visible light PCs available. Phenoxazine PCs can be tuned for long excited state lifetimes, high triplet yields, and redox reversibility, properties advantageous for photocatalysis. Phenoxazine PCs have been demonstrated as an effective drop-in replacement for Irppy₃ in many cases and even outperforming Irppy₃ in some applications.

- Technical Details
Phenoxazine PCs are strong excited state reductants capable of reducing alkyl and aryl halides via an electron transfer mechanism. The alkyl radicals formed can partake in substitution or addition reactions on unsaturated vinyl or aromatic groups e.g., atom transfer radical polymerization, atom transfer radical addition and trifluoromethylation. This class of PCs can also activate Ni co-catalyst for C-N, C-S, C-O and C-C aryl cross-coupling reactions. In the case of C-N cross-coupling, spectroscopic evidence suggests that phenoxazine PC activates a Ni-amine co-catalyst via an energy transfer mechanism. Additionally, these PCs have been demonstrated in solar fuel generation converting CO₂ to methane, thus closing the carbon cycle.
