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. Light therapy: Fluorescence emission and reactive oxygen species generation are greatly enhanced in a molecular phthalocyanine-quencher system upon interaction with glutathione (see figure). Its activation has also been demonstrated in vivo. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
