Claims18
A method for producing ground state atomic oxygen [O(3P)] and an oxidation product, the method comprising illuminating a mixture comprising a polycyclic aromatic selenoxide and an oxygen accepting substrate with light to produce ground state atomic oxygen and an oxidation product, wherein the light has a wavelength of from about 370 nm to about 900 nm, wherein the polycyclic aromatic selenoxide has a structure of Formula (Ia), (Ib), (IIa), (IIb), (IIIa), (IIIb), (IVa), or (IVb):
- wherein R1, R2, R3, R4, R5, R6, R7 and R8 are each independently hydrogen, hydroxy, substituted or unsubstituted hydrocarbyl, or substituted or unsubstituted amino and n is 1 or 2.
A compound of Formula (Ia) or (Ib):
- wherein R1 and R2 are each independently hydrogen, hydroxyl, substituted or unsubstituted hydrocarbyl, or substituted or unsubstituted amino and n is 1 or 2.
A compound of Formula (IIa) or (IIb):
- wherein R3 and R4 are each independently hydrogen, hydroxyl, substituted or unsubstituted hydrocarbyl, or substituted or unsubstituted amino and n is 1 or 2.
