| Abstract: | A stereoselective solid surface has been created by the self-assembly of a chiral osmium complex, λ-Os(phen)3](ClO4)2 (phen=1,10-phenanthroline), onto a single layered clay film deposited on an indium tin oxide (ITO) electrode; the OsII–OsIII redox couple mediates the electrochemical oxidation of chiral 1,1′-2-binaphthol in a stereoselective way or the S-isomer is oxidized at 1.4 times higher rate than the R-isomer. |
