Md. Barboiu et al., Functionalized derivatives of benzocrown-ethers, V - Multiple molecular recognition of zwitterionic phenylalanine, TETRAHEDRON, 55(30), 1999, pp. 9221-9232
The synthesis of the polytopic receptor 4-(4'-benzo- 18-crown-6-sulfonamido
)benzo-15-crown-5 is reported. This polytopic receptor provides multiple mo
lecular recognition of zwitterionic phenylalanine through different non-cov
alent bonds. Active membrane transport mechanisms by bulk liquid membranes
of the phenylalanine are presented as a function of the co-transported alka
li cation. (C) 1999 Elsevier Science Ltd. All rights reserved.
