H. Graubaum et al., SYNTHESIS AND TRANSPORT INVESTIGATIONS OF DIOXAPOLYAZACALIX[4]ARENES AND TRIAZINO CROWN-ETHERS, Journal fur praktische Chemie, Chemiker-Zeitung, 340(2), 1998, pp. 165-170
Synthesis and characterisation of new dioxapolyazacalix[4]arenes 5a-c
and triazino crown ethers 9a-i are described. The structures and confo
rmations of these novel macrocyclic ring systems have been investigate
d by various NMR methods. Transports of metal ions across a liquid mem
brane are also reported.
