Resumen
Cette thèse porte sur la modélisation des propriétés structurales, aromatiques et spectroscopiques d'une nouvelle classe de macrocycles alternatifs aux porphyrines, les azacalixphyrines (ACPs). Ces macrocycles conjugués, synthétisés et caractérisés pour la première fois en 2010 par le groupe d’Olivier Siri à Marseille, ont montré des propriétés exceptionnelles (structure, absorption, tautomérie, et complexation). Cette thèse vise à proposer de nouveaux dérivés aux propriétés améliorées, notamment en ce qui concerne leur absorption, en utilisant les outils offerts par la chimie théorique. Parmi

Resumen
Monoclonal antibody fragments (Fab') which recognise tumour-associated antigens provide an ingenious means of selectively targeting a therapeutic radionuclide to a tumour for radioimmunotherapy. The radionuclide yttrium-90, a long range β(^-) emitter, was chosen to deliver a sterilising dose of radiation to the tumour. A selection of novel functionalised macrocyclic ligands based on a 1,4,7,10-tetraazacyclododecane skeleton have been synthesised, and the stabilities of their yttrium (III) and gadolinium (III) complexes studied in vitro through association and dissociation measurements, and in

Resumen
The work reported in this thesis is divided into two distinct areas. The first involves the synthesis of monoaza- and diaza-[12]-ring macrocycles, with differing side-arm N-substituents. The twelve-membered macrocycles possess a convenient ring-size for exploring the stability and selectivity of complexation of small cations, in particular those from groups IA and IIA. Amide substituents on nitrogen were expected to function as effective σ-donors to cations with high charge density (e.g. Li (^+), Ca (^2)(^+)), because of their high ground state dipole moments.

Monoclonal antibodies which recognise tumour-associated antigens provide a means of targeting radionuclides selectively to tumour cells.

The synthesis of functionalised macrocycles for binding these four radioisotopes to antibodies is described. In each case, a macrocycle has been selected to provide a complex which is kinetically inert, thereby preventing dissociation of the radiolabel in vivo.

With the goal of developing Schiff base macrocycles with conjugation extended over multiple aromatic rings, new phenanthrene and triphenylene-containing bis(salicylates) were synthesized. A convenient route to 3,6,9,10-tetraalkoxy-2,7-diiodophenanthrene was developed. This compound has been found to be a useful precursor for Pd-catalyzed cross-coupling reactions. Macrocycles were synthesized by Schiff base condensation of the phenanthrene and triphenylene precursors. Reaction of smaller phenanthrene and triphenylene bis(salicylates) with 1,2-dialkoxy-4,5-phenylenediamine afforded macrocycles

Macrocyclic natural products are conformationally restricted molecules that often have improved ability to bind with high affinity and selectivity on a target. Within macrocycle chemistry, macrolactone formation is a particularly challenging transformation and has spurred the development of highly diverse synthetic strategies. A key strategy that is missing is a chemoenzymatic approach to this challenge, and the logical place to look for such a catalyst is the thioesterases (TEs) from the biosynthetic pathways that generate these molecules in Nature.

Single walled carbon nanotubes (SWCNTs) have unique physical, optical and electronic properties. Current production methods provide SWCNTs as a polydisperse mixture, with respect to helicity, diameter and length, and cannot be tuned to yield a discrete SWCNT isomer. A bottom up approach would yield a single SWCNT, which would allow for a better understanding of how chemical modification affects a carbon nanotube’s properties. Synthesis by this route has yet to be accomplished. Phenylene ethynylene macrocycles were synthesized by a stepwise linear fashion and cyclooligomerization. These

Resumen
Conjugated Schiff-base macrocycles are interesting compounds of interest as platforms for catalysis, the preparation of novel synthetic ion channels and potentially as porous or tubular discotic liquid crystals. The preparation of organic macrocycles is typically low yielding, with polymerization competing with cyclization; the use of imines derived from the condensation of an aldehyde and an amine provides a means by which to conduct cyclizations under thermodynamic control and thereby improve yields. The use of difunctional aldehydes and amines allows for the formation of macrocycles in high
