(Matrix Presented) The effect of anion templation is investigated for the photodimerization of a thymine-functionalized isothiouronium receptor. The receptor forms a photodimer at the thymine moiety in methanol upon UV irradiation, while the isothiouronium moiety works as an oxoanion binding site via a two-point hydrogen-bonding motif. As compared to the case of a free receptor, the presence of pyrophosphate (PPi) resulted in the preferential formation of the syn-type photodimer, which would be desirable for recognizing the templated PPi.
