Abstract The ionisable chromoionophores5 were synthesised from simple precursors. These chromoionophores extract alkali metal cations from aqueous solutions at pH 〉 7 into dichloromethane. The ratio of extraction coefficients for the chromoionophore5c for K+ and Na+ indicate that it has potential for use in optical fibre sensors for K+ in the presence of Na+, Mg2+ and Ca2+ at extracellular concentrations.
