Abstract

It was found that 1,3-alternate-calix[4]arenes having cavities composed of two oxygens and two benzene rings show the metal affinity much higher than cone-calix[4]arenes having a cavity composed of four oxygens. The unexpected finding is most likely rationalized in terms of the "π-donor participation" in the metal complexation.
