摘 要:The total rate constants of the reaction of six antioxidants with singlet oxygen were measured by fluorospectroscopy,and the effects of these antioxidants on the photostability of the dyes were also investigated *** results reveal that the six antioxidants are the effective quenchers of singlet oxygen (~1O_2)and can increase the photostability of the *** power of metal chelates to quench ~1O_2 is the strongest,and the chelates show the most effects on the photostability of the *** photostability of the dyes has something to do with the relative amount of the antioxidant used.
