Intra and intermolecular interactions in cyclophanes


In this project we will study the electronic structure and the inter- and intermolecular interactions in cyclophanes of different sizes, by use of electronic density analysis, energy decomposition techniques, as well as the analyse the aromaticity of the studied systems. Initially, the 2,3 cycloalkanes will be studied to clarify the role of through space and through bond interactions in the properties of these compounds. The exocyclic complexes of these compounds with RuNO and FeCo should be addressed. Also, electronic spectra, excited states and chemical bonding should be studied. After obtaining a deep understanding of these systems, we should analyze the chemical bonding and aromaticity of polycationic macrocycles (MPs), systems with immense scientific and technological importance. The changes caused by the variation of the oxidation states of the MPs and their interaction with charge donor or acceptor compounds should be studied. (AU)
