Conclusions 1. The introduction of phenyl substituants into the p-benzoquinone molecule lowers the energy of the lowest singlet and triplet ππ* states. The lowest triplet states for 2-phenyl- and 2,6-diphenyl-l,4-benzoquinone are ππ* states. 2. The lifetime of triplet aryl-substituted p-benzoquinones in liquid solutions increases as the energy of the lowest triplet ππ* state decreases owing to an increase in the contribution from this state to the lowest triplet state of the quinone.
