Fund Project: This project was financed by Jiangxi Boyuan Industry Co. Ltd. (Jiangxi Province, China). Thanks to Professor Wenting Hua and Professor Hongcheng Gao (Peking University, China) for their suggestions on the photochemical interaction mechanism of MgTPP with oxygen.

The photochemical reaction of magnesium tetraphenyl porphyrin(MgTPP) with O₂ was studied in CH₂Cl₂ by steady-state fluorescence,UV-vis absorption,FTlR and MALDI-TOF MS measurements.These spectra indicate that O₂ can react with Mg TPP excited by irradiation.forming the stable 1:1 coordinated adduct of MgTPP-O₂.In the adduct,the oxygen atoms of O₂ may insert in the Mg-N bonds in MgTPP and birid with the nitrogen atoms of MgTPP to form N-O-Mg bonds.
