Abstract
The effect of added surfactants, sodium dodecylsulfate (SDS), Triton X-100 (C 8 H 17 C 6 H 4 (OCH 2 CH 2 ) x OH, x=9, 10), and cetyltrimethylammonium bromide (CTAB), on measured rate constants for electron transfer between Co(terpy) 2 2+ and a series of cobalt(III) complexes, [Co(phen) 3 ] 3+ , [Co(5-Cl-phen) 3 ] 3+ , [Co(5-Me-phen) 3 ] 3+ , [Co(5,6-Me 2 -phen) 3 ] 3+ , [Co(5-SO 3 -phen) 3 ], and [Co(dipic) 3 ] 3+ , varying in ligand structure and ionic charge, have been determined by stopped-flow spectrophotometry. The observed rate catalysis or inhibition, resulting from micellar interactions, has been rationalized using the Berezin model
