Abstract
The synthesis of three cross-conjugated macrocycles bearing pyridine functionality is described. The ability of two of these molecules, 5a and 5c, to behave as 4,4'-bipyridine mimics in self-assembly reactions is demonstrated by axial coordination to a metalloporphyrin. The directed coordinative ability of the pyridine rings ensures predictable self-assembly into well-ordered nanoscale systems, both in solution and the solid state. 1H, 13C, and HMQC NMR spectroscopic experiments and ESI MS have been used to characterize the supramolecular complexes in solution. X-ray crystallographic analysis of solid-state assemblies 7a and 7c provides insight into the scope and flexibility of these macrocyclic ligands as supramolecular building blocks. UV-vis and fluorescence spectroscopies provide a description of their electronic characteristics.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
