Supramolecular Walls from Cyclic Peptides: Modulating Nature and Strength of Weak Interactions
Bibliographic record
Abstract
Both macrolactams cyclo-[NH−CH 2 −C≡C−CH 2 −C(Me) 2 -CO] n ( n = 3 and n = 2) have been synthesized and crystallized. They have respectively one intramolecular hydrogen bond and no such bond. Both macrocycles self-assemble as parallel supramolecular walls with or without inclusion of solvent between them. The units of the former ( n = 3) are held together by NH···π/NH···OC interactions, whereas they are glued by a very dense network of classical parallel-oriented hydrogen bonds, involving all the amides of the rings, in the latter ( n = 2). In that case, the bulky C(Me) 2 groups are located on the surface of the walls and can be held responsible for the piling process of the layers, by means of attractive van der Waals interactions. This spatial arrangement recalls the 3D structure of cellulose, where all constitutive sheets stack mostly via van der Waals forces.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
