Singlet oxygen was detected from the reaction of lophine hydroperoxides 2 in the presence of 1,3‐diphenyl‐isobenzofuran as a singlet oxygen detector. In order to examine the substituent effect on the formation of 1 O 2 , 2‐( p ‐substituted phenyl) lophine peroxides 2a–c were tested. It was found that an electron‐attracting group contributed to the efficient formation of 1 O 2 (80% for a NO 2 group), while an electron‐donating group enhanced the efficiency of chemiluminescence.
