Abstract
A series of dansylated sterically hindered amines designed to trapping reactive oxygen species, were synthesized. Compounds were tested in i solated thylakoid membranes subjected to photoinhibition by excess pho tosynthetically active radiation (400-700 nm). DanePy showed good sele ctivity for singlet oxygen and the formation of nitroxide was detected by appearance of ESR signal and quenching fluorescence. (C) 1998 Else vier Science Inc.
