Proline-functionalised calix[4]arene: an anion-triggered hydrogelator.
نویسندگان
چکیده
A water-soluble, chiral calix[4]arene has been found to form hydrogels when triggered by the presence of specific anions, with efficacy linked to the Hofmeister series; the gel properties are modified by the associated cations, and gelation can be reversibly switched off by increasing pH.

Self-inclusion of proline-functionalised calix[4]arene leads to hydrogelation.
Solution-phase and solid-state structural studies indicate that the remarkable hydrogelation properties of a proline-functionalised calix[4]arene emerge as a result of extended helical structures formed via inclusion of a proline moiety in a neighbouring calixarene cavity.
متن کاملIon pair-induced conformational motion in calix[4]arene-strapped calix[4]pyrroles.
In order to understand the still-poorly understood interplay between calix[4]arene conformations and cation and anion recognition in multicomponent systems, the ion pair receptors 1 and 2 were synthesized. In solution and in the solid state, the calix[4]arene subunit of receptor 1 adopts a cone conformation, while that of 2 interconverts between the cone and the partial cone conformation. These...
متن کاملAnion-templated calix[4]arene-based pseudorotaxanes and catenanes.
We present the rational design and anion-binding properties of the first anion-templated pseudorotaxanes and catenanes in which the "wheel" component is provided by a calix[4]arene macrobicyclic unit. The designs and syntheses of two new calix[4]arene macrobicycles, 2 and 3, are presented, and the abilities of these new species both to bind anions and to undergo anion-dependent pseudorotaxane f...
متن کاملIon channel formation from a calix[4]arene amide that binds HCl.
The ion transport activity of calix[4]arene tetrabutylamide 1,3-alt 2 was studied in liposomes, planar lipid bilayers, and HEK-293 cells. These experiments, when considered together with (1)H NMR and X-ray crystallography data, indicate that calix[4]arene tetrabutylamide 2 (1) forms ion channels in bilayer membranes, (2) mediates ion transport across cell membranes at positive holding potential...
متن کاملThe Solid-State Complex of para-Sulphonato-Calix[8]Arene Anion with Dimethylammonium Cations
The solid-state structure of the complex para-sulphonato-calix[8]arene – dimethylammonium – dimethylformamide shows the para-sulphonato-calix[8]arene anion in a pleated cone conformation with the inclusion of four dimethylammonium cations and the dimethylformamide positioned exo to the macrocycle.
