Abstract
Ionophoric biscalix[4]arenyl nitriles in which the lower rims are linked vi
a a single site on each calixarene were synthesized. Their complexing abili
ties were studied by the liquid-liquid extraction of alkali (Li+, Na+, K+,
and Cs+) and selected transition metal (Cu2+, Co2+,Cd2+, Ni2+, and Hg2+) ca
tions. We found a novel selectivity of these compounds toward Hg+2 cations
through examination of the extraction.
