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.
