From Millimeter to Subnanometer: Vapor–Solid Deposition of Carbon Nitride Hierarchical Nanostructures Directed by Supramolecular Assembly
Bibliographic record
Abstract
Abstract Shape and nanostructure control has great potential to enable graphitic carbon nitride (C3N4) structures with new properties and functionalities. In this work, a new type of hierarchically structured nanoporous C3N4 is introduced. The C3N4 exhibits unique, edelweiss‐like morphology, with components ranging from millimeter‐sized bunches to subnanometer‐thick layers. A one‐step vapor–solid deposition approach using supramolecular aggregates as the precursor is carried out to accomplish the growth. Supramolecular pre‐association plays a crucial role in achieving this nanostructure by directing the vaporization and deposition processes. Furthermore, very small C3N4 quantum dots can be readily acquired by bath sonication of the thin layers in water. The supramolecular preorganization growth strategy developed herein may provide a general methodology in the design of advanced photoelectric materials with broad applications in energy conversion and storage.

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.
