چکیده

A calixpyrrole bearing a tethered imidazolium functional group was prepared in the form of its bromide salt. This compound was found to undergo self-assembly to produce supramolecular polymers, wherein both the bromide anion and the imidazolium cation are bound to the calixpyrrole core.

Molecular recognition and self-assembly special feature: Self-assembly of dimeric tetraurea calix[4]pyrrole capsules.

Calix[4]pyrroles having extended aromatic cavities have been functionalized with 4 ureas in the para position of their meso phenyl substituents. This elaboration of the upper rim was completed in 2 synthetic steps starting from the alpha,alpha,alpha,alpha-tetranitro isomer of the calix[4]pyrrole obtained in the acid catalyzed condensation of p-nitrophenyl methyl ketone and pyrrole. In dichlorom...

Bis-cation salt complexation by meso-octamethylcalix[4]pyrrole: linking complexes in solution and in the solid state.

Pyridinium and imidazolium bis-cations are shown to link calix[4]pyrrole anion complexes both in solution and in the solid state. This is accomplished by binding of the bis-cations to the electron-rich bowl shaped cavities formed by two separate calixpyrrole-anion complexes. These resulting sandwich-type structures provide a new way of organising calix[4]pyrrole anion complexes in space.

Calix[n]imidazolium as a new class of positively charged homo-calix compounds

Macrocycles based on neutral calixarenes and calixpyrroles have been extensively explored for ion binding, molecular assembly and related applications. Given that only these two types of calix compounds and their analogs are available, the introduction of new forms of widely usable calix macrocycles is an outstanding challenge. Here we report the quadruply/quintuply charged imidazole-based homo...

Reconciling Experiment and Theory in the Use of Aryl-Extended Calix[4]pyrrole Receptors for the Experimental Quantification of Chloride–π Interactions in Solution

In this manuscript we consider from a theoretical point of view the recently reported experimental quantification of anion-π interactions (the attractive force between electron deficient aromatic rings and anions) in solution using aryl extended calix[4]pyrrole receptors as model systems. Experimentally, two series of calix[4]pyrrole receptors functionalized, respectively, with two and four ary...

Synthesis and binding pattern of Calix[4]Pyrrole compounds

In this short review, focus has been on the improvisations in the synthetic procedures of the Calix[4] pyrrole type compounds, since their first discovery in the year 1886 and subsequent discussion on their binding pattern towards different chemical species. Calix[4] pyrrole, which is an analogue of hetero calixarenes, is the representative of a group of macrocycles. It has an ability to bind n...
