説明
<jats:title>Abstract—</jats:title><jats:p>The E ⇆ Z photoisomerization of the title compound (UA) (a naturally occurring sunscreen) has been studied in aqueous solution. At a UA concentration of 6m<jats:italic>M</jats:italic> and using 313nm excitation, φ<jats:sub>E→z</jats:sub>= 0.52, φ<jats:sub>Z→E</jats:sub>= 0.47 and the photostationary state is 34% E. Under these conditions, loss of UA is minimal. Low energy triplet quenchers fail to impede the isomerization, but the reaction can be induced by several triplet sensitizers. The E<jats:sub>T</jats:sub> for UA is estimated to be approximately 55 kcal/mol.</jats:p>
