dc.description.abstract This paper explores the liquid crystal and aggregation properties of Bordeaux Dye along with a more general theory of aggregation. Common properties of chromonic liquid crystal systems have been expounded upon and re-evaluated. X-ray data were used to find the aggregate's cross-sectional area, which was compared to that of a single molecule to show that the structure of the aggregates is more complicated than a single-molecule stack. Theoretical aggregate size calculations show that it is important to account for the rotational partition function term, and these aggregate size distributions, along with a simple function found by exploring exciton theory, allow us to analyze the absorption coefficient verses concentration data to find the stacking free energy. A phase diagram for this molecule has also been produced and is compared to those of other chromonic systems. en
