Closing the Loop: Triazolylpyridine Coordination Drives the Self‐Assembly of Metallomacrocycles with Tunable Topologies for Small‐Molecule and Guanine‐Quadruplex Recognition
Bibliographic record
Abstract
The 2-(1,2,3-triazol-4-yl)pyridine motif, with its facile "click" synthesis and remarkable coordinative properties, is an attractive chelate for applications in the metal-directed self-assembly of intricate three-dimensional structures. Organic ligands that bear two such chelates bridged by flexible hinge moieties readily undergo self-assembly with metal ions of different coordination geometries to generate a series of topologically diverse metallomacrocycles that can be used for numerous applications. Herein, the synthesis and self-assembly of one such ligand with zinc(II), copper(II), and palladium(II) ions is reported, and the stability of the resulting metallomacrocycles described. An investigation into the use of these metallomacrocycles for the recognition of both small-molecule substrates, such as deoxyguanosine monophosphate, and larger biological assemblies, such as DNA and RNA guanine quadruplexes, is also described.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
