Synthesis and Transport and Ionophoric Properties of α,ω-Diphosphorylated Azapodands: XII. Membrane Transport of Organic Acids by Diphosphorylated Diamines and Diazapodands

Аннотация

Membrane transport of mono- and polyfunctional carboxylic acids mediated by phosphorylated diamines has been studied. The structure of complexes transferred through the membrane has been discussed; in some cases, a relation has been found between the efficiency of membrane transport of organic acid substrates and the structure of membrane carriers and their complexes with the acids. A correlation between the transmembrane flow and shift of some characteristic IR absorption bands (as well as change of their intensity) of the substrate–carrier complexes in comparison to the corresponding substrates and carriers has been estimated.
