Abstract

The present invention relates to photochemical singlet oxygen generators useful as bleaching agents for laundry detergent compositions or in hard surface cleaning compositions and as anti-microbials. The photochemical singlet oxygen generators comprise a heavy atom unit-containing axial unit wherein the heavy atoms overlap with the π electron cloud of the photosensitizer unit and enhance the quantum efficiency of the transition of an electron from exited singlet state to triplet state.
