Octa-<i>O</i>-Methoxy Resorcin [4] Arene Amberlite XAD-4 Polymeric Chelating Resin for Solid Phase Extraction, Preconcentration, Separation and Trace Determination of Ni(II), Cu(II), Zn(II) and Cd(II) Ions

“…Calix [4] resorcinarenes possess good capability to form a variety of complexes with organic/inorganic ions, neutral molecules, transition metal complexes and organometallics [72] for the simple reason that they can be functionalized at the upper rim or at C-methyl position or at hydroxyl groups at extra-annular position, enabling them to be used as multifunctional receptors [73]. Literature reveals only few reports on the extraction of metal ions using calyx [4] resorcinarene and its derivatives [74][75][76][77][78][79][80].…”

Trimeric and hexameric calixarene-based capsules

“…The present review is a continuation of our paper dealing with dimeric capsules 14 ; our previous works concern cavitands, [15][16][17] calixarenes as metal ion receptors 18,19 as well as resorcinarenes 20 and calixpyrroles. 21 The efficient synthesis of capsules which are large enough to entrap various guests is a great challenge.…”

Octafunctionalized calix[4]resorcinarene-N-fenil-acetohydroxamic acid for the separation, preconcentration and transport studies of cerium(IV)

“…The calixresorcinarenes are unique three-dimensional cyclic tetramer and hexamer that belong to a class of metacyclophanes in which resorcinol units are linked by methylene bridges. 3 The interest towards this class of compounds which are capable of forming host guest complexes is stimulated by the development of supramolecular chemistry which uses them for the possible creation of synthetic receptors and carriers of cations, anions and neutral molecules. 4 The host properties of calix [4]resorcinarenes continue to draw research interests due to its potential application as macrocyclic receptors, 5 as dendrimers in biological systems, 6 nano-capsule, 7 nanoparticles, 8 optical chemosensors, 9 supramolecular tectons, 10 host molecules, 11 as components in liquid crystals, 12 photoresists, 13 selective membranes, 14 surface reforming agents, 15 HPLC stationary phases, 16 as ion channel mimics, 17 and metal ion extraction agents.…”
