It was found that tetra‐ o ‐acyl riboflavins efficiently photosensitize the monomerization of the cis, syn ‐cyclobutane dimers of 1,3‐dimethylthymine and 1,3‐dimethyluracil in aqueous solution in the presence of such anionic surfactants as sodium dodecyl sulfate and sodium hexadecyl sulfate at concentrations higher than their critical micelle concentration, while little monomerization of the dimers was photosensitized by the flavins in the absence of the surfactants and even in the presence of cationic and nonionic surfactants.
