This chapter deals with those members of the calix[n]arene family having a number n of aryl rings ranging from 7 to 20, which have been defined as the "large" calixarenes. In particular, their synthesis, chemical modification, and supramolecular properties are here reviewed. Notwithstanding their unfavorable common features (the lack of efficient large-

Liquid Crystalline Calixarenes
Journal of Inclusion Phenomena and Molecular Recognition in Chemistry, 1994Bowl-shaped (bowlic) liquid crystals are reviewed and new bowlic materials containing rigid tungsten-oxo calix[4]arene based cores are discussed. Tungsten-oxo calix[4]arenes with 8 and 12 dodecyloxy sidechains have been investigated and exhibit bowlic columnar phases which are stable over approximately a 200° temperature range.

Catenation of Calixarene Annulus
Organic Letters, 2012Through-the-annulus-catenated calixarenes have been obtained, for the first time, by exploiting the "superweak anion" approach that allows the threading of the calix cavity with functionalized dialkylammonium axles. In addition, the first example of a stereoprogrammed synthesis of a catenane orientational isomer (an oriented calix[2]catenane) has been ...

Abstract The term calix[n]arenes indicates a class of phenolic metacyclophanes derived from the condensation of phenols and aldehydes. The name was coined by Gutsche and derives from the Latin ‘calix’ because of the vase-like structure that these macrocycles assume when all the aromatic rings are oriented in the same direction.

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.
