The inclusion of atoms other than carbon into the framework of polycyclic conjugated hydrocarbons can have profound effects on the properties of the resultant compounds. Substitution of acenes with nitrogen-, oxygen-, and sulfur-containing rings has long been used as a strategy to alter the HOMO and LUMO energy levels of a compound and direct the solid-state morphology. In this thesis, I present my work in extending heteroatom substitution into the class of compounds known as indenofluorenes.
Chapter I serves as an overview of indenofluorenes and related compounds with a special focus on the redox properties of these materials. Chapter II covers the synthesis and characterization of two selenophene-containing indenofluorene analogues. Chapter III discloses a new synthetic method for the preparation of unsymmetrical indenofluorenes and discusses the unusual reactivity of the dione precursors. Chapter IV is a comprehensive study of indacenodibenzothiophenes. This chapter investigates how heteroatom substitution affects the antiaromaticity of the indacene core and presents a detailed optoelectronic, computational, solid-state and materials study of a series of indacenodibenzothiophene derivatives. Chapter V presents my work towards the synthesis of the final unknown indenofluorene isomer, indeno[1,2-a]fluorene. Appendices A and B discuss my work done as part of Professor Shih-Yuan Liu’s research group at the start of my graduate career.
