Metal ions recognition by 1,2,3-triazolium calix[4]arene esters synthesized via click chemistry

Fluorescent phenanthridine-based calix[4]arene derivatives: synthesis and thermodynamic and computational studies of their complexation with alkali-metal cations

“…15,16 On the other hand, their abilities for complexation of alkali-and alkaline earth metal cations have been far less explored, despite the fact that they are capable of binding such cations quite efficiently, 17 and in some cases with remarkable selectivity. 18 It should be noted that the process of calixarene-cation complex formation in solution is oen strongly inuenced by solvation of the reactants and the complex formed. [19][20][21][22][23][24][25] In addition, in non-aqueous solutions ion-pairing between free and complexed cation and an anion can signicantly affect the cation-binding reaction.…”

Calixarene‐Based Chemosensors by Means of Click Chemistry

“…with alkynylcalixarene. [19] The cooperative complexation ability of the triazoles and ester groups towards alkali-metal ions was investigated. Alkali-metal ions were selectively detected in the presence of picrate ions in the aqueous phase as shown by the UV spectra of 4.…”

A reação "click" na síntese de 1,2,3-triazóis: aspectos químicos e aplicações

“…130 A CuAAC também está envolvida em outras modificações de calixarenos. [131][132][133] Os macrociclos também são importantes blocos construtores em química supramolecular, devido às suas diversas aplicações como cavidades moleculares e receptores artificiais. As reações de macrociclização de estruturas lineares contendo uma função azida e outra alcino são altamente dependentes da probabilidade de encontro dos dois grupos reativos envolvidos na ciclização.…”
