Computations on non-covalent assemblies: Supramolecular organization and transport properties
2022
The aim of this Thesis is to rationalize, from a theoretical perspective, the structural, electronic, optical and transport properties of different electroactive non-covalent assemblies of special relevance in the field of organic electronics. The ultimate goal is to establish valuable supramolecular structure-property relationships. In particular, this Thesis is focused on three types of systems: hole transporting materials (HTM), donor–acceptor supramolecular complexes and supramolecular polymers. For each system, the spotlight has been put on different relevant electronic processes. In the first part, the structural organization of several supramolecular polymers is studied. In particula…
The “nitrogen effect” : Complexation with macrocycles potentiates fused heterocycles to form halogen bonds in competitive solvents
2023
Weak intermolecular forces are typically very difficult to observe in highly competitive polar protic solvents as they are overwhelmed by the quantity of competing solvent. This is even more challenging for three-component ternary assemblies of pure organic compounds. In this work, we overcome these complications by leveraging the binding of fused aromatic N-heterocycles in an open resorcinarene cavity to template the formation of a three-component halogen-bonded ternary assembly in a protic polar solvent system. peerReviewed
Halogen bonding and host-guest chemistry between
2019
Single crystal X-ray structures of halogen-bonded assemblies formed between host N-hexylammonium resorcinarene bromide (1) or N-cyclohexylammonium resorcinarene chloride (2), and 1,4-diiodooctafluorobutane and accompanying small solvent guests (methanol, acetonitrile and water) are presented. The guests’ inclusion affects the geometry of the cavity of the receptors 1 and 2, while the divalent halogen bond donor 1,4-diiodooctafluorobutane determines the overall nature of the halogen bond assembly. The crystal lattice of 1 contains two structurally different dimeric assemblies A and B, formally resulting in the mixture of a capsular dimer and a dimeric pseudo-capsule. 1H and 19F NMR analyses …
Halogen bonding and host–guest chemistry between N-alkylammonium resorcinarene halides, diiodoperfluorobutane and neutral guests

Od scenografii teatralnej do scenografii społeczno--politycznej
2020
The paper is an attempt at comprehensive conceptualization of the category of ‘social and political scenography’. The author’s reference point are artistic practices (institutional theater, field theater, happenings), various performances, rituals of social life (e.g. funerals), public assemblies, including religious ones, but also different forms of unconventional participation (manifestations, demonstrations). The concept of “performance” was adopted as the common denominator of all these practices. The author tried to prove the thesis, that the social scenography (just like contemporary theater scenography) was not only a decorative background for collective social activities, artistic p…
Gra o regiony’2018. Wybory do sejmików województw
2020
Monografia jest kolejną z cyklu publikacji przygotowywanych przez zespół politologów z większości ośrodków akademickich w Polsce a dotyczących wyborów do sejmików województw. Jej celem jest analiza rywalizacji w elekcji samorządowej na poziomie regionalnym w 2018 r. Zasadnicze pytania, na jakie autorzy starają się odpowiedzieć dotyczą charakteru podmiotów politycznych/ komitetów wyborczych uczestniczących w rywalizacji, wzorców rekrutacji kandydatów na listy wyborcze oraz przygotowywanych i realizowanych przez podmioty strategii i taktyk w kampanii wyborczej. Szczególna uwaga została poświęcona rezultatom wyborów, które są analizowane wieloaspektowo w celu uchwycenia kierunków ewolucji regi…
