An HPLC system combining a chemiluminescence detector was applied to estimate the singlet oxygen ( 1 O 2 ) generation ability of di‐sulfonic phthalocyanine zinc (ZnPcS 2 ) isomers. As photosensitizers, ZnPcS 2 produces 1 O 2 in air‐saturated solutions under photoirradiation. The latter reacts with methyl Cypridina luciferin analogue (MCLA) to initiate chemiluminescence. This photoinduced chemiluminescence (PCL) of MCLA provides an easy method for evaluating the isomers' 1 O 2 generation ability during a simultaneous HPLC separation procedure. The cis ‐isomers and trans ‐isomers of ZnPcS 2 show different 1 O 2 generation abilities, which are in accordance with differences in their absorption spectra.
