title: Hypericin hydroquinone: potential as a red-far red photosensitizer?
abstract: Hypericin hydroquinone is the product of two-electron reduction of hypericin (quinone), a potent phenanthroperylenequinone photosensitizer. In contrast to the quinone, the hydroquinone exhibits strong absorbance in the far-red spectral region. Herein we provide initial evidence on the potential of hypericin hydroquinone as a far-red photosensitizer.
