Abstract

fetched live from OpenAlex

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
