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-

Deprotonation of Calixarenes in Acetonitrile
The Journal of Organic Chemistry, 2005[Structure: see text]. The pKa values for calixarenes in MeCN have been determined by selective titration with bases using a spectroscopic method. These values are as follows: calix[4]arene pKa(1) = 19.06 +/- 0.22, pKa(2) > 33; calix[6]arene pKa(1) = 15.59 +/- 0.06, pKa(2) = 23.85 +/- 0.35, pKa(3) > 33; calix[8]arene pKa(1) = 17.20 +/- 0.20, pKa(2 ...

The synthesis in 1985 by the group led by Tony McKervey of numerous calix[4]arene derivatives capable of acting as neutral, multidentate ligands proved to be a seminal step in the development of various applications of calixarenes as metal-ion binding agents.

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.

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 ...

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.

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 ...
