Abstract :
The first representatives of 1,3-alt-thiacalix[4]arene bis(crown-5 and -6) ethers were synthesized by the cyclocondensation of thiacalix[4]arenes with tetraethylene glycol ditosylate and 1,14-diiodo-3,6,9,12-tetraoxatetradecane, respectively. The complexing abilities of ligands were determined by alkali (Na+, K+, Rb+, Cs+) picrate extraction methods.
