Abstract
The study of traditional organic cavitands has been central in the development of supramolecular chemistry. As the field of supramolecular chemistry matures, a new class of cavitand, the metallocavitand, is quietly emerging. No central theme currently exists to unify these relatable supramolecules due to the structural diversity of metallocavitands. To provide a concrete foundation for future metallocavitand research, we define metallocavitands here as multimetallic complexes where metal coordination is necessary for cavity formation. This tutorial review highlights synthetic routes based on self-assembly and macrocycle-templating strategies to isolate bowl-shaped metallocavitands, and highlights interesting supramolecular phenomena observed with metallocavitands such as dimerization, host-guest encapsulation, catalysis, unique regioselective reactivity, and enantioselective guest recognition.

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
