Calixarenes. 24. Complexation by water-soluble calixarenes
The Journal of Organic Chemistry, 1990Synthese de deux calixarenes a partir du p-(dialkylamino)calixarene (n=4-8) (I) par un processus utilisant le p-quinonemethide impliquant le traitement d'un sel quaternaire de I avec 2 equivalents de diethyl malonate de sodium, suivi d'une hydrolyse et decarboxylation du polyester ...

Topics in calixarene chemistry
Journal of Inclusion Phenomena and Molecular Recognition in Chemistry, 1989Several facets of calixarene chemistry have been investigated including the mechanism of their formation by the base-induced condensation of phenols and formaldehyde, procedures for introducing functional groups onto the ‘upper rim’ and ‘lower rim’ of calixarenes, the conformational behavior of calixarene oxyanions, the formation of complexes in ...

Photo-CIDNP studies on calixarenes and bridged calixarenes
J. Chem. Soc., Chem. Commun., 1987A comparison of the photo-CIDNP spectra of calix(4)arenes (1) and bridged calix(4)arenes (2) shows that a certain degree of flexibility is necessary for a rapid intramolecular hydrogen transfer from the hydroxy groups of phenolic units to adjacent phenoxyl radical units.

Functionalization and Application of Calixarenes
1995Selectively functionalized calix[4]arenes are used to build effective receptors for cations, anions and neutral molecules or for a combination of a cation and an anion. This was done by combination with a terphenyl unit (cation receptor), a uranyl-containing salen moiety (for anionic and neutral guests) or by introduction of sulfonamide groups (anion ...

Study of Calixarenes, V. Friedel‐Crafts Reaction of Calixarenes
Chemische Berichte, 1994AbstractThe para‐acylation of calix[4]arene (2), calix[6]arene (3), and calix[8]arene (4) by Friedel‐Crafts reaction with a wide variety of acyl chlorides leads to 5–7 in moderate to good yields. Friedel‐Crafts reaction of 26,28‐dimethoxycalix[4]arene (8) gave products 9 selectively disubstituted in the para‐positions of phenol rings.

The anchoring of functional organic coatings on the surface of inorganic nanoparticles has been and still is the topic of intense research activity for the development of novel nanomaterials. Within this context metal nanoparticles decorated with synthetic receptors have been quite extensively employed to further expand the scope of supramolecular ...

Calixarenes in Action is unique among books devoted to this interesting class of synthetic macrocycles. Rather than emphasizing the molecular properties of calixarenes, it covers in depth their supramolecular functions, enlightening the reader as to the peculiar features of calixarenes as hosts and as platforms for the synthesis of more complex ...
