Abstract: The invention relates to photochemical singlet oxygen generators useful as bleaching agents or anti-microbial agents in laundry detergent compositions or in hard surface cleaning compositions. The singlet oxygen generators described herein have enhanced singlet oxygen generation due to aromatic moieties teed to the molecules, said aromatic moieties absorbing ultra violet radiation then re-emitting the radiation as fluorescence at a wavelength absorbable by the singlet oxygen producing photosensitizer unit. The increase in the number of photons having an absorbable wavelength provides an increase in the production of singlet oxygen.
