Methanol‐swollen Nafion beads were used as microreactors to control the photochemical reaction pathways. Product selectivity in three unimolecular reactions, namely, the photo‐Fries rearrangement of naphthyl esters, Norrish Type I reaction of 1‐phenyl‐3‐ p ‐tolyl‐propan‐2‐one and Norrish Type I and Type II reactions of benzoin alkyl ethers were examined. The influence of cations over the photodimerization of acenaphthylene and cross‐photodimerization between acenaphthylene and N‐benzyl maleimide included within Nafion were also examined. The photochemical behaviors of the above substrates were significantly altered within Nafion compared with their solution photochemistry. Of particular interest, the product distributions were found to depend on the counter cations of Nafion.
