Synthesis and crystal structure of new coordination polymers based on sodium aqua complexes and macrocyclic cavitand cucurbit[6]uril

Supramolecular lanthanide assemblies with cucurbit[6]uril: from synthesis and crystal structure to application

“…The IR spectra of complexes 1–10 are typical of cucurbit[6]uril-containing compounds 10,19,47,48 and are consistent with the findings of structural analysis (Fig. 3S†).…”

“…The presence of polar carbonyl groups in CB[6] enables the formation of complexes with oxophilic metals via hydrogen bonding or direct coordination with metal aqua complexes. 16–22…”

“…The presence of polar carbonyl groups in CB [6] enables the formation of complexes with oxophilic metals via hydrogen bonding or direct coordination with metal aqua complexes. [16][17][18][19][20][21][22] Supramolecular assembly has recently been proved to be an efficient way of fabricating smart photofunctional materials. In this method, well-ordered architectures bearing novel photophysical properties are formed spontaneously from individual chromophore components by noncovalent interaction or self-aggregation.…”

Structure and thermodynamic properties of adducts based on cucurbit[6]uril and Fe(III)/Fe(II) aqua complexes: A DFT examination

“…Syntheses and study of the adducts formed as a result of reactions between CB[n] and various organic and inorganic particles have been carried out by several groups, notably by that of Fedin [14][15][16][17][18][19][20][21][22]. This research resulted in the discovery of unique possibilities for the use of CB [n] in various fields.…”

“…The study reported in [20] examined complexes of CB [7] and amino acids, and special attention was paid to the formation of an inclusion compound through the stage of adduct formation. An analysis of [14][15][16][17][18][19][20][21][22] shows that, along with a wide range of experimental methods, theoretical methods of quantum chemistry provide important insights needed to better understand the mechanism of the process. For instance, the formation of an adduct based on CB [7] and an iridium aqua complex was examined using quantum chemistry methods in the context of the inhibition of the process of catalytic oxidation of water by the metal complex, which is of interest for energy technologies [23].…”
