摘要：

pH dependent absorption and fluorescence spectra of hypericin 1 and its octahydroxy analogue 3 demonstrate their acidic properties, their deprotonation occurring in the ground and excited states from OH in the bay region and in the peri position to the carbonyl, respectively; the presence of the anion of 1 in the crystalline state is established by X-ray diffraction.
