Abstract:

2011 - 2012<br>Recently, Neri et al have introduced an efficient method to obtain endo-cavity complexation and through-the-annulus threading of large calixarenes exploiting the inducing effect of a weakly coordinating anion, tetrakis [3,5-bis (trifluoromethyl) phenyl]borate (TFPB-). In this PhD thesis this approach has been used for the synthesis of [2]rotaxanes, which showed an unprecedented inversion of the wheel orientation. Subsequently, it was extended to the synthesis of pseudo[3]rotaxane systems in which two calix[6]arene macrocycles are threaded by a bis(benzylalkylammonium) axl

Regulation of transmembrane ion transport is a vital aspect in the maintenance of a healthy organism. To understand how this highly selective process occurs, how it can become impaired and how impairment may be treated, model compounds are useful tools. Several systems are presently being explored but one of the most widely applicable combines a rigid macrocycle, capable of size-based ion recognition, with membrane spanning substituents that allow the target ions to transverse a phospholipid bilayer. The calixarene class of macrocycles is ideally suited to this task. Previous work had shown th

Le travail présenté dans ce manuscrit inclut la synthèse organique des différents types de calixarènes, l'étude de leurs propriétés optiques, des simulations théoriques pour déterminer leurs conformations favorables et leurs utilisations pour stabiliser des nanoparticules. Des nanoparticules d’argent, d’or, de platine et des nanoparticules bimétalliques (Ag-Au) ont été synthétisées en utilisant par réduction radiolytique ainsi que la synthèse la photochimique. Ces nanoparticules sont stabilisées en utilisant des calixarènes et divers polymères. Les nanomatériaux ont été caractérisés par spectr

Abstract:

The conditions required for formation of unusual bottlebrush-shaped lanthanoid coordination clusters were investigated. The known clusters are supported by tetrazole-functionalised p-t-butylcalixarenes, and carboxylate co-ligands. It was confirmed that the lighter lanthanoids form mononuclear complexes, and heavier lanthanoids form bottlebrush clusters. Changing the carboxylate co-ligand had little impact on the complexes formed. Altering the structure of the calixarene had a significant impact. When the t-butyl group was replaced with hydrogen or allyl groups, mononuclear complexes formed.

Abstract:

The first part of this thesis reports the synthesis of five calixarene molecules and their incorporation into ISEs as thallium(I) selective ionophores for use in clinical and environmental analysis. Four calix[4]arene molecules were successfully synthesized. Two were isolated in the cone conformation with iso-propyl groups attached to the lower rim. The other two were in the 1,3-alternate conformation with allyl groups attached to the phenolic oxygen. The final calixarene synthesized was a calix[6]arene that was partially substituted with iso-propyl groups on the lower rim. The parallel orient
