A zinc(II) phthalocyanine substituted with a 2,4-dinitrobenzenesulfonate group has been prepared. Its fluorescence emission and reactive oxygen species generation can be greatly enhanced by glutathione in phosphate-buffered saline and inside MCF-7 cells. This compound thus functions as a highly efficient molecular-based activatable photosensitizer.
