摘要：
New azobenzene crown ether p-tert-butylcalix[4] arenes (6 and 7) have been synthesized by reductive coupling reactions between two nitrobenzene groups. Their isomerization and switchable binding properties towards Na+ and K+ were studied by H-1 NMR spectroscopy. The results showed that Na+ preferred to bind the cis form of 6 while K+ preferred to bind the trans isomer. (C) 2000 Published by Elsevier Science Ltd.
