The location of heavy halogen atoms (Br and I) in fluorescein derivatives noticeably affected the performance of photoinitiated free‐radical polymerization. We previously demonstrated that 2’,4’,5’,7’‐tetrahalogen fluoresceins (i.e., eosin Y and erythrosine B) increased the polymerization performance in this order: fluorescein < eosin Y < erythrosine B. We, however, observed in this work that a tetrahalogen‐substituted benzoic acid group in fluorescein considerably decreased the performance in this order: fluorescein > 4,5,6,7‐tetrabromofluorescein > 4,5,6,7‐tetraiodofluorescein.
