Abstract

The triplet-triplet absorption spectrum of 1,5-diaminoanthraquinone is reported in methanol, together with triplet lifetimes in various solvents. The triplet lifetimes in linear alcohols correlate well with the solvent polarity parameter ET(30) of the alcohols. The transient spectrum of 1,5-diaminoanthraquinone in deuterated ethanol is broader than the spectrum in ethanol. The triplet lifetime of the deuterated species is twice that observed in ethanol.
