Developing 1,10-phenanthroline complexes towards their application as triplet sensitizers

Abstract

Summary - Chapter 1: This chapter begins with a general introduction to polycyclic aromatic hydrocarbons, followed by a focused review of recent 3,8-substituted 1,10-phenanthroline systems reported in the literature. The chapter also describes the synthesis a series of 3,8-aryl acetylene 1,10-phenanthroline ligands via a sequence of Sonogashira cross-coupling and Diels-Alder cycloaddition reactions, and the issues surrounding the use of copper catalysts in cross-coupling reactions with 1,10-phenanthrolines. The characterisation and spectroscopic properties of the ligands are discussed. In addition, brief computational investigations of both the neutral and protonated pyrene functionalised 1,0-phenanthroline ligand are also presented.
