TY - THES A1 - Renner, Rebecca T1 - Aggregation, Chirality and Reduction of Nonplanar Polycyclic Aromatic Hydrocarbons T1 - Aggregation, Chiralität und Reduktion Nichtplanarer Polyzyklischer Aromatischer Kohlenwasserstoffe N2 - Within this thesis the interactions between novel corannulene derivatives in solution as well as in the solid state by changing the imide residue of a literature known extended corannulene dicarboximide were investigated, in order to obtain a better understanding of the packing and possible charge transport in potential applications. Accordingly, the goal of the work was to synthesize and investigate an electron-poor corannulene bis(dicarboximide) based on previously published work but with higher solubility and less steric encumbrance in imide position to enable self-assembly in solution. To obtain further insights into the conformational stability, structure and chiroptical properties of heavily twisted PBIs another aim of this thesis was the design, synthesis, and optoelectronic investigation of various fourfold directly arylated PBIs by substitution in bay position with smaller hydrocarbons with different steric demand, i.e., benzene, naphthalene and pyrene, which should be separable by chiral high performance liquid chromatography (HPLC). As of yet, no concise study concerning the optical and electronic properties of differently core-substituted PBIs in the neutral as well as the mono- and dianionic state in solution is available, which also elucidates the origin of the different optical transitions observed in the absorption and emission spectra. Thus, in this thesis, the investigation of five PBI derivatives with different frontier energetic levels to produce a reference work of reduced PBIs was tackled. N2 - Im Rahmen dieser Arbeit wurden die Wechselwirkungen zwischen neuartigen Corannulen-Derivaten sowohl in Lösung als auch im festen Zustand durch Veränderung des Imid-Restes eines literaturbekannten annulierten Corannulen-Dicarboximids untersucht, um ein besseres Verständnis der Packung und des möglichen Ladungstransports in potentiellen Anwendungen zu erhalten. Dementsprechend war es das Ziel der Arbeit, ein elektronenarmes Corannulenbis(dicarboximid) zu synthetisieren und zu untersuchen, das auf bereits veröffentlichten Arbeiten basiert, jedoch eine höhere Löslichkeit und weniger sterischen Anspruch in der Imidposition aufweist, um die Selbstorganisation in Lösung zu ermöglichen. Um weitere Einblicke in die Konformationsstabilität, Struktur und chiroptischen Eigenschaften von stark verdrillten PBIs zu erhalten, war ein weiteres Ziel dieser Arbeit das Design, die Synthese und die optoelektronische Untersuchung verschiedener vierfach direkt arylierter PBIs durch Substitution in Bucht-Position mit kleineren Kohlenwasserstoffen mit unterschiedlichen sterischen Anforderungen, z.B. Phenyl, Naphthalin und Pyren, die durch chirale Hochleistungsflüssigkeitschromatographie (HPLC) trennbar sein sollten. Bisher gibt es noch keine übersichtliche Studie über die optischen und elektronischen Eigenschaften von unterschiedlich kernsubstituierten PBIs im neutralen sowie mono- und dianionischen Zustand in Lösung, die auch den Ursprung der unterschiedlichen optischen Übergänge in den Absorptions- und Emissionsspektren aufklärt. In dieser Arbeit wurde daher die Untersuchung von fünf PBI-Derivaten mit unterschiedlichen energetischen Eigenschaften in Angriff genommen, um ein Referenzwerk reduzierter PBIs zu erstellen.

The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy lepton collider (FCC-ee), the corresponding 100km tunnel infrastructure, as well as the physics opportunities of these two colliders, and a high-energy LHC, based on FCC-hh technology. This document constitutes the third volume of the FCC Conceptual Design Report, devoted to the hadron collider FCC-hh. It summarizes the FCC-hh physics discovery opportunities, presents the FCC-hh accelerator design, performance reach, and staged operation plan, discusses the underlying technologies, the civil engineering and technical infrastructure, and also sketches a possible implementation. Combining ingredients from the Large Hadron Collider (LHC), the high-luminosity LHC upgrade and adding novel technologies and approaches, the FCC-hh design aims at significantly extending the energy frontier to 100TeV. Its unprecedented centre of-mass collision energy will make the FCC-hh a unique instrument to explore physics beyond the Standard Model, offering great direct sensitivity to new physics and discoveries.

We compute the next-to-leading (NLO) contributions due to QED and purely weak corrections and implement them into a fully differential Monte Carlo event generator, which is available for first experimental studies. We show representative phenomenological results of interest for the MUonE experiment and examine in detail the impact of the various sources of radiative corrections under different selection criteria, in order to study the dependence of the NLO contributions on the applied cuts. The study represents the first step towards the realisation of a high-precision Monte Carlo code necessary for data analysis.
