Silver and thallium ion complexation with allyloxycalix[4] arenes
Couton, Daniel,Mocerino, Mauro,Rapley, Chris,Kitamura, Chitoshi,Yoneda, Akio,Ouchi, Mikio
, p. 227 - 229 (2007/10/03)
A series of six calix[4]arene derivatives bearing allyl groups and/or benzyl groups functionalized at the phenolic oxygen atoms were synthesized and their cation-binding abilities for silver(I) and thallium(I) ions were evaluated through solvent extractio

This paper reports a systematic experimental and theoretical study of the second-order nonlinear optical properties of multichromophoric molecules that range from dipolar symmetry to three-dimensional octupolar symmetry. The four possible conformers of te
An Easy Access to Tetra-O-Alkylated Calixarenes of Cone Conformation
Bitter, Istvan,Gruen, Alajos,Agai, Bela,Toeke, Laszlo
, p. 7835 - 7840 (2007/10/02)
Fully O-alkylated calixarenes have been synthesized by the alkylation of p-tert-butylcalixarene and its 1,3-dialkylated derivatives in liquid-liquid phase-transfer catalytic process. 1H4 and 1H2R2 could effeciently be deprotonated by aqueous NaOH (5
Syntheses of all possible conformational isomers of O-alkyl-p-t-butylcalix[4]arenes
Iwamoto, Koji,Araki, Koji,Shinkai, Seiji
, p. 4325 - 4342 (2007/10/02)
In p-t-butylcalix[4]arene (1H4) and its mono-, di-, tri-, and tetra-O-alkyl derivatives (1HR3, 1H2R2, 1HR3, and 1R4 respectively), 23 different homologs can exist (including 1H4)
Syntheses of New Isomers from p-t-Butylcalixarene. Strategies for Regioselective Alkylation on the Lower Rim
Iwamoto, Koji,Yanagi, Akihiro,Araki, Koji,Shinaki, Seiji
, p. 473 - 476 (2007/10/02)
By using a protection-deprotection technique and metal template effects, a number of new regio- and conformational isomers were synthesized.
