Synthesis and transport investigations of dioxapolyazacalix[4]arenes and triazino crown ethers

Graubaum,Costisella,Dambowsky

, p. 165 - 170 (2007/10/03)

Synthesis and characterisation of new dioxapolyazacalix[4]arenes 5a-c and triazino crown ethers 9a-i are described. The structures and conformations of these novel macrocyclic ring systems have been investigated by various NMR methods. Transports of metal ions across a liquid membrane are also reported.
