Filed:

Sep 14, 1981

Appl. No.:

6/302033

Inventors:

A. Paul Schaap - Detroit MI

International Classification:

C01B 1300

US Classification:

423579

Abstract:

This invention relates to production of singlet oxygen and includes means and methods for storage and retrieval thereof as well as continuous production from ground state oxygen. With respect to storage and retrieval of singlet oxygen, certain aromatic acceptor compounds are oxidized to yield solid endoperoxides which, in turn, are decomposed to yield singlet oxygen and regenerate the acceptor. Continuous production of singlet oxygen occurs through irradiation of dye sensitizers with electromagnetic radiation causing activation thereof and excitation of flowing ground state oxygen.

Abstract:

A solid phase photosensitizer and method of use for photochemical generation of singlet oxygen. The sensitizer comprises one or more layers of an organic polycrystalline dye solid which absorbs radiant energy to release triplet excitons. Where multiple layers are employed, triplet state energies of the layers decrease toward the outer surface. A sub-monomolecular surface layer of organic molecules has a triplet state energy which is less than that of the adjacent dye-solid layer but greater than that of molecular oxygen. The sub-monomolecular layer thus functions to trap exciton energy at the sensitizer surface for reaction with gaseous molecular ground state oxygen directed thereover.
