摘要：

A carrier admixture of phenylboronic acid and ionophore (cryptand or crown ether) simultaneously cotransports p-nitrophenyl beta-glucopyranoside, M(+) and OH- through a liquid organic membrane. The transport mechanism involves the apparent self-assembly of a lipophilic ion-pair, comprising of anionic, phenylboronate-glucopyranoside adduct and metal cation-ionophore complex. Active glucopyranoside transport (i.e. uphill transport against a concentration gradient) was achieved in the direction of a metal cation concentration gradient.
