Inside Cover: Counterion-Controlled Self-Sorting in an Amphiphilic Calixarene Micellar System (Chem. Eur. J. 19/2016)

An amphiphilic calixarene receptor forms inclusion complexes with an organic guest, with sodium cations present in solution as counterions. Upon micellization of the receptor molecules, the sodium ions are attracted to the Stern layer leading to an increase in their local concentration and neutraliz...

Description
Summary:An amphiphilic calixarene receptor forms inclusion complexes with an organic guest, with sodium cations present in solution as counterions. Upon micellization of the receptor molecules, the sodium ions are attracted to the Stern layer leading to an increase in their local concentration and neutralization of the receptor negative charges. As a net result, the organic guest is translocated to the micellar interior while the sodium ions occupy the calixarene cavity. The present system illustrates a self‐sorting driven self‐assembly and counterion binding. More information can be found in the Communication by N. Basílio, L. García‐Río et al. on page 6466 ff.
