Using picosecond absorption spectroscopy it has been shown that in Rhodobacter sphaeroides reaction centres the substitution of the primary quinone acceptor (QA), ubiquinone-10, by other quinone species (with redox potentials higher or lower than that of ubiquinone-10) has essentially no modifying e

โฆ Synopsis
The synthesis of 4 and 9, in which two porphyrins are joined by a biquinoxalinyl bridge and by a quinoxaline Tr6ger's base, respectively, provide systems which have interpoq)hyrin centre-centre and edge-edge distances that very closely match those between the primary donor -primary acceptor tetrapyrrolic pair in bacterial photosynthetic reaction centres.
