摘要：

Peroxotitanium(IV) tetraphenylporphyrin, O2TiIV-TPP, in a benzene solution undergoes photoreaction to yield oxotitanium(IV) tetraphenylporphyrin N-oxide, O=Ti(IV)TPPO. The quantum yield for the formation of O=Ti(IV)TPPO is observed to be 0.095 +/- 0.05 in the excitation wavelength range shorter than 430 nm. It is found that O=Ti(IV)TPP=O in ethanol demetalates to yield tetraphenylporphyrin N-oxide, H2TPPO.
