This thesis is divided into four chapters. Chapter 1 will show progress towards a review
of applications utilizing the pyrene core to show the utility of one of the most studied
molecules in chemistry is far from fully realized. Chapter 2 shows a monomer‐through-pentamer
series of oligo(1,8‐pyrenylene)s was synthesized using a two‐step iterative synthetic
strategy. The trimer, tetramer and pentamer are mixtures of atropisomers that interconvert
slowly at room temperature (VTNMR analysis). They are classified as functional molecular
liquids (FMLs) well below room temperature, as indicated by POM, DSC and SWAXS
analysis. The oligomers are highly fluorescent both in the liquid state and in dilute solution
and an investigation of their photophysical properties demonstrated that delocalization plays
a larger role in their excited states than it does in related pyrene‐based oligomers. Chapters 3
and 4 outline progress in using the oligomers as starting points for different molecular systems
will also be covered, attempting to put more ‘F’ in the FMLs
