Opis: A special feature of organic compounds with an extended π bonding system is their ability to undergo electron transfer (redox) reactions, corresponding to possible electron transitions taking place between energy levels in electrically charged and inert compounds, which, in turn, depend on their chemical structure and the conjugation length of the π-conjugated bond. For large macromolecular π-conjugated systems, the way to exercise control over both variables is to select small-molecule π-conjugated units, having the desired electrical properties, and copolymerise them with saturated spacers to obtain macromolecules equipped with regular π-unsaturated bond breaks. Functionalisation of the spacers themselves opens additional possibilities for shaping the properties of those copolymers, including their solubility or amorphousness, providing tools for tailoring their macroscopic physicochemical features, which, in turn, are important from the point of view of processing them into ordered thin-film structures used as active layers in electrochromic devices, like electrochromic filters, electroluminescent cells or diodes and photovoltaic cells.
Research tasks of the student involved in this topic will involve laboratory organic synthesis of target π-conjugated structures equipped with selected saturated spacers. Work will be carried out in direct cooperation with the doctoral student scientific assistant. This research topic should appeal to all interested in synthesis of organic compounds and their subsequent chemical modification on a preparative laboratory scale.
