The cis–trans photoisomerization of 5-styryl-1,3-dimethyluracil is investigated. The fluorescence and photoisomerization quantum yields in various solvents of different viscosity and polarity, the effect of salt, pH, and heavy atom on the fluorescence and photoisomerization, the triplet sensitization of the photoisomerization, and the azulene quenching of the direct and sensitized isomerization indicate the singlet mechanism for the direct photoisomerization of the compound. The laser flash photolysis at room temperature showed a weak triplet–triplet absorption indicating some intersystem crossing from the excited singlet state to the triplet state.
