Abstract

The synthesis of several macrocycles containing two bipyrazolic subunits, with different cavity sizes and with donor-group-bearing side arms attached, is reported. Their alkali cation binding ability has been studied from two aspects: extraction and transport through an artificial liquid membrane. Macrocycles described here show a high selectivity towards Li+ and Na+ cations; furthermore one of them is remarkably well adapted to extract selectively ...
