Two-component self-assembly of a tetra-guanidiniocarbonyl pyrrole cation and Na4EDTA: formation of pH switchable supramolecular networks.
نویسندگان
چکیده
A guanidiniocarbonyl pyrrole (GCP) cation forms stable H-bond assisted ion pairs with carboxylates even in aqueous solutions. A tetra GCP cation 1 undergoes efficient two-component self-assembly with Na4EDTA, a tetra-carboxylate, leading to 3D supramolecular networks. These networks show dual pH responsiveness and reversibly dissociate back into monomers upon addition of either acid or base.

Guanidiniocarbonyl-pyrrole-aryl derivatives: structure tuning for spectrophotometric recognition of specific DNA and RNA sequences and antiproliferative activity
We present here a systematic study of different guanidiniocarbonylpyrrole-aryl derivatives designed to interact with DNA or RNA both by intercalation of an aromatic moiety into the base stack of the nucleotide as well as groove binding of a guanidiniocarbonyl pyrrole cation. We varied 1.) the size of the aromatic ring (benzene, naphthalene, pyrene and acridine), 2.) the length and flexibility o...
متن کاملHalogen bonded Borromean networks by design: topology invariance and metric tuning in a library of multi-component systems.
A library of supramolecular anionic networks showing Borromean interpenetration has been prepared by self-assembly of crypt-222, several metal or ammonium halides, and five bis-homologous α,ω-diiodoperfluoroalkanes. Halogen bonding has driven the formation of these anionic networks. Borromean entanglement has been obtained starting from all the four used cations, all the three used anions, but ...
متن کاملMolecular basis of cooperativity in pH-triggered supramolecular self-assembly
Supramolecular self-assembly offers a powerful strategy to produce high-performance, stimuli-responsive nanomaterials. However, lack of molecular understanding of stimulated responses frequently hampers our ability to rationally design nanomaterials with sharp responses. Here we elucidated the molecular pathway of pH-triggered supramolecular self-assembly of a series of ultra-pH sensitive (UPS)...
متن کاملA short, rigid linker between pyrene and guanidiniocarbonyl-pyrrole induced a new set of spectroscopic responses to the ds-DNA secondary structure.
A novel pyrene-guanidiniocarbonyl-pyrrole dye, characterised by a short, rigid linker between the two chromophores, interacts strongly with ds-DNA but only negligibly with ds-RNA. Under neutral conditions the dye shows strong selectivity toward AT-DNA (with respect to GC-DNA). Binding is accompanied by a specific ICD band at 350 nm and fluorescence quenching for all DNAs/RNAs studied. At pH 5 t...
متن کاملAn imidazolium-functionalized self-assembling calix[4]pyrrole.
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.
