Abstract
Thermolytic reactions of 9,10-diphenylanthracene endoperoxide (1) and its derivatives having deuterated phenyl groups and phenyl groups with fluorinated substituents were investigated as chemiluminescence (CL) reactions proceeding by heating crystal samples. While heated crystals of 1 showed negligible CL, CL emissions from singlet oxygen (1O2) generated by thermolyses of the derivatives were observable in the heated solid-liquid mixture states, indicating that the modifications for the derivatives were effective to suppress the 1O2 deactivation.
