Abstract

The pyrazole-containing 18-membered crown ether 1, which possesses a less-bulky substituent on the sp3 nitrogens and not only the sp2 nitrogen, but also the carbonyl groups as ligating points, exhibited excellent ability as an ionophore for a NH4+-selective electrode. The value of the selectivity coefficient of an ion-selective electrode (ISE) containing 1 for the NH4+ ion with respect to an interfering K+ ion was 6.3×10-2. This result is superior to that of ISE based on an antibiotic substance, nonactin (1.2×10-1).
