Lors de ce travail de thèse nous nous sommes intéressés à deux thèmes principaux dans le but de fabriquer des matériaux conducteurs chiraux : la synthèse de TTF-hélicènes présentant une chiralité hélicoïdale moléculaire, ainsi que l’obtention de molécules de symétrie 3 à base de TTF ayant la capacité à former des auto-assemblages supramoléculaires hélicoïdaux. Dans la partie TTF-hélicène, plusieurs tailles d’hélicènes ont été envisagées avec pour objectif d’obtenir des énantiomères stables et séparables. Ils ont été caractérisés par diffraction de rayons X, de même que les sels obtenus par électrocristallisation. De plus, une étude théorique de la réaction de photocyclisation des stilbènes en hélicènes a été menée pour comprendre sa régiosélectivité. Les molécules de symétrie 3 sont composées d’un coeur BTA-DABP sur lequel sont fixés des TTF avec leurs substituants chiraux. L’assemblage colonnaire des molécules est étudié par CD et les fibres formées sont observées par microscopie ce qui permet de déterminer leur hélicité. On varie le cœur ainsi que les groupements fixés dessus. / In this work, we have been interested in two different topics to make chiral conducting materials: the synthesis of TTF-helicenes, with molecular helical chirality, as well as the formation of three-fold symmetry molecules based on TTF units able to self-assemble into supramolecular helical aggregates. For the TTF-helicenes, several lengths of helicenes are considered in order to form stable and separable enantiomers. They are characterized by X-ray diffraction just as the salts that are obtained by electrocrystallization. Moreover, a theoretical study of the photocyclisation reaction of stilbenes into helicenes was performed to understand its regioselectivity. The three-fold symmetry molecules are composed of a BTA-DABP core on which TTF with chiral substituents are fixed. The assembly into columnar aggregates is followed by CD and the fibers formed are observed by microscopy in order to determine their helicity. Variation of the core and the substituents are made.

As a key contributor to the current discussion of the Catholic theology of religions, Gavin D'Costa's writings represent a consistent attempt to utilize the resources of the doctrine of the Trinity to address a number of issues regarding the theological significance and function of religions in the salvific plan of God. The aim of this thesis is to examine critically his Trinitarian theology of religions through the lens of a main proponent of patristic theology, Basil of Caesarea, and through a historical-systematic study, address the question of whether his underlying Trinitarianism is consonant with classical Trinitarian theology. After a discussion of Vatican II and post-Conciliar sources, the main contours of D'Costa's theology are highlighted through an interpretive grid of particularity/universality (Christology/Pneumatology) with a second-order universality/particularity. Despite his distancing from the three-fold typology of exclusivism-inclusivism-pluralism, we analyzed that much of his theology continues to fall within the category of traditional inclusivism, particularly since his recent proposal of the limbo of the Fathers contained serious difficulties pertaining to his intention to maintain a singular OT Judaism-Christianity relationship. Next, we examined the main features of Basilian Trinitarianism, and proposed that three major themes are of relevance for a comparative analysis with D'Costa's theology, namely, (1) the doctrines of divine simplicity and inseparable operations, (2) the enlightening work of the Spirit, and (3) the theology of baptism and theosis. Throughout the discussion, in recognition that Basil's thought is part of the patristic theological matrix of his time, we will also reference the writings of other Church Fathers, including Gregory of Nyssa, Gregory of Nazianzus, and Augustine. We concluded that while in Basil's theology, economy, relationality and ethics are intricately woven into each other, D'Costa's system, despite its significant merits, was at risk of disaffiliating the connections between the three.
