中文摘要facilitated ion transfer reactions of 20 amino acids with di.benzo-18-crown-6 (db18c6) at the water/1,2-dichloroethane (w/dce) interfaces supported at the tips of micro- and nano-pipets were investigated systematically using cyclic voltammetry. it was found that there were only 10 amino acids, that is, leu, val, ile, phe, trp, met, ala, gly, cys, gln (in brief), whose protonated forms as cations can give well-defined facilitated ion transfer voltammograms within the potential window, and the reaction pathway was proven to be consistent with the transfer by interfacial complexation/dissociation (tic/tid) mechanisms. the association constants of db 18c6 with different amino acids in the dce (beta(0)), and the kinetic parameters of reaction were evaluated based on the steady-state voltammetry of micro- or nano-pipets, respectively the experimental results demonstrated that the selectivity of complexation of protonated amino acid by db18c6 compared with that of alkali metal cations was low, which can be attributed to the vicinal effect arising from steric hindrance introduced by their side group and the steric bulk effect by lipophilic stabilization.
