Résumé :

A little bit of flexibility: Charged or neutral species can be accommodated in solution and in the solid state by the closed hydrophobic cavity of the first calix[6]arene to adopt a 1,3,5-alternate conformation (see picture, Boc=tertbutoxycarbonyl). The encapsulation involves an induced-fit process that is reminiscent of the rotation of a door and is characterized by large activation barriers for guest exchange. © 2009 Wiley-VCH Verlag GmbH & Co.
