New meta-functionalised 1,3-diethynylbenzene Multi-Centre Ruthenium Organometallics

Abstract

This work focussed on elucidation of structure-property relationships of novel ruthenium-alkynyl complexes towards understanding associated trends in observed linear and nonlinear optical behaviour. Chapter One introduces the different concepts and mechanisms, such as electron communication and non-linear optics, that were targeted for investigation by the structures synthesized for this thesis. This begins with a brief comparative analysis of trends found in similar bridging structures to the 1,3-diethynylbenezne bridge complex. Chapter 2 and 3 details the bulk of the work undertaken - synthesis of novel ruthenium meta-functionalized 1,3-diethynylbenzne mono- and poly-metallic complexes, and the results of the their associated nuclear magnetic spectral, linear optical spectral, electrochemical, spectroelectrochemical, and computational investigations. Each are followed by a discussion of the trends uncovered. The chapter starts with a brief introduction to planar conjugated macrocycles. Each chapter ends when a conclusion of the work undertaken and indicates possible pathways for extending the research in future work. The thesis ends with the all the supporting information collected in the sythesis of the new organic compounds and inorganic complexes, and the raw data collected in the characterisation of these complexes. There are also the graphs and tables of the results of the nuclear magnetic spectral, linear optical spectral, electrochemical and spectroelectrochemical experiments and iso-surface plots and transition data for the computational investigations.
