Impact of multiple cation-pi interactions upon calix[4]arene substrate binding and specificity.


The cation-pi interaction influence on the conformation and binding of calix[4]arenes to alkali-metal cations has been studied using a dehydroxylated model. The model allows for the separation of cooperative cation-pi and electrostatic forces commonly found in the binding motifs found in calixarene complexes. Starting from the four well-known calix[4]arene… (More)
