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.

摘要

在作为单线态氧探测器的1,3 - 二苯基异苯并呋喃存在下，从洛粉碱氢过氧化物2的反应中检测到了单线态氧。为了研究取代基对单线态氧（¹O₂）形成的影响，测试了2 - （对 - 取代苯基）洛粉碱过氧化物2a - c。结果发现，吸电子基团有助于高效形成¹O₂（对于硝基基团为80%），而供电子基团提高了化学发光效率。
