Abstract
The longest-wavelength absorption bands of unprotonated piperidinoanthraquinones are charge-transfer in type, but on protonation of 1-piperidinoanthraquinone the band becomes n→π*, accompanied by marked differences in photosensitizing behaviour between unprotonated and protonated forms.Keywords
