M. Selkti et al., The first example of a substrate spanning the calix[4]arene bilayer: the solid state complex of p-sulfonatocalix[4]arene with L-lysine, CHEM COMMUN, (2), 2000, pp. 161-162
The complex of p-sulfonatocalix[4]arene with l-lysine shows a new type of i
ntercalation behaviour with regard to the achiral hydrophobic bilayer assem
bly of the calixarenes, and represents the first structural example of a ca
tionic organic substrate spanning such a bilayer.
