The ability to trap an active superoxide anion radical generated in the photo system Ⅱ(PSII) and the stability of their spin adduct of DEPDMPO as well as three previously reported traps DMPO, DEPMPO and M 3PO were comparatively analyzed according to their chemical structures. In addition, the effects of 2 methyl and \%α\% phosphoryl substituted analogues of DMPO on the stabilities of the corresponding spin adduts were systematically展开更多

The results show that the title compound is stable, the geometry calculated by AM1 is in good agreement with experimental results. The atoms of O(1),O(15), O(19),O(20) in the molecule bond easily with metallic atoms. So the title compound can form stable complex with rare earth metal ions.展开更多
