Abstract
The photophysical properties of some methyl substituted alloxazines in water are reported. Excited singlet and triplet have been studied and excited singlet state relaxation in the absence of oxygen shown to be dominated by non-radiative relaxation pathways. In the presence of oxygen, efficient singlet oxygen generation is observed. The observed photophysica are discussed in terms of the hydrogen bonding nature of the solvent. © 2002 Elsevier Science B.V. All rights reserved.
