Sensing of antipyretic carboxylates by simple chromogenic calix[4]pyrroles.

Synthesis, structure, anion binding, and sensing by calix[4]pyrrole isomers.

The synthesis, structure, and anion binding properties of chromogenic octamethylcalix[4]pyrroles (OMCPs) and their N-confused octamethylcalix[4]pyrrole isomers (NC-OMCPs) containing an inverted pyrrole ring connected via alpha'- and beta-positions are described. X-ray diffraction analyses proved the structures of two synthesized isomeric pairs of OMCPs and NC-OMCPs. The addition of anions to so...

Results and Discussions

Calix (4) pyrroles are macromolecules structurally related to porphyrins, they exhibit exceptional chemical and physical properties that have suggested a vast number of potential applications in host-guest chemistry. In recent years, calix (4) pyrroles have attracted a lot of attention because of their properties as binders of anions, transition metals, and neutral substrates and their new appl...

Syntheses of calix[4]pyrroles by amberlyst-15 catalyzed cyclocondensations of pyrrole with selected ketones.

A facile and efficient protocol is reported for the synthesis of calix[4]pyrroles and N-confused calix[4]pyrroles in moderate to excellent yields by reaction of dialkyl or cycloalkyl ketones with pyrrole catalyzed by reusable Amberlyst(TM)-15 under eco-friendly conditions.

Chromogenic silica nanoparticles for the colorimetric sensing of long-chain carboxylates.

Silica nanoparticles functionalized with chromogenic spirobenzopyran and thiourea subunits show selective colour changes in the presence of certain long-chain carboxylates.
