Abstract

Abstract2‐Ethylhexylpoly(trimethylene 1,3‐phosphate) (3), poly(1,2‐glycerol phosphate) (1) and poly‐(1‐acetoxy‐2,3‐glycerol phosphate) (2) were synthesized and used as synthetic analogues of teichoic acids. Their properties as a carrier of magnesium and calcium ions were examined in the competitive exchange diffusion process with the countertransport of hydrogen or sodium ions. It turned out that polymers with 1,2‐glycerol phosphate units (1,2) exhibit lower ability to transport preferentially magnesium ions than poly(1,3‐alkylene phosphate)s (3). In all cases the efficiency of polyphosphates in preferential transport of magnesium ions is higher when transport is coupled with proton counterflow.
