Synthesis and Properties of Functional π-systems for Supramolecular Chemistry and Advanced Materials

Martin Drøhse Kilde

Abstract

This Thesis presents synthesis, characterization and study of advanced molecular and supramolecular systems. The project has been based on synthetic organic chemistry used to create novel systems, to potentially in time to cover, problems within today’s society. These systems have been creatively designed in which the architectures should obtain specific functionalities. The work has focused on synthesis and properties of functional π-systems of advanced optical and redox-active molecules for light-harvesting and electron transport. Chapter 2 Bottom-up synthesis and electronic properties of segments of the elusive 6,6,12-graphyne for advanced materials. Chapter 3 Synthesis, properties and charge transport measurement of organic molecular wires are presented. Chapter 4 Synthesis and preliminary properties of a [2]rotaxane consisting of a redox-active tetrathiafulvalene, the photo-/thermo couple dihydroazulene/vinylheptafulvene and cyclobis(paraquat-pphenylene). Chapter 5 Synthesis and properties of a combination of the two photo-/thermoswitches; norbornadiene/quadricyclane and dihydroazulene/vinylheptafulvene. Chapter 6 Synthesis and preliminary properties of a calix[4]pyrrole, a receptor for anions, and the photo-/thermoswitch dihydroazulene/vinylheptafulvene. Chapter 7 Synthesis of a strapped calix[4]pyrrole ion- pair receptor for use as an ion-pair carrier. Appendix A Fluorescence switching with subphthalocyanine-dihydroazulene dyads. Appendix B Molecular solar thermal systems – control of light harvesting and energy storage by protonation/deprotonation.
