Abstract

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.

Singlet oxygen ( 1 O 2 ) can be generated in a living cell upon focused laser irradiation of the intracellular photosensitizers. 1 O2 lifetime in the living cells is shortened by the reactions with cellular molecules, and thus the 1 O2 diffusion in a single cell has attracted much attention.
