Özet
A new calixcrown-6 oligomer 5 was synthesized by reacting a 1,3-distal di-amino derivative of cone p-tert- butylcalix[ 4] crown-6 with malonyl dichloride. Extraction studies with precursor monomers 2 and 3 and oligomer 5 showed differences in their metal cation extraction behavior and selectivity. Precursors monomers 2 and 3 were selective for Hg2+; whereas, oligomer 5 showed high affinity towards both alkali (Li+, Na+, K+, and Cs+) and heavy metal cations (Cu2+, Cd2+, Hg2+ and Pb2+).
