Aza-diphosphazenanes: Inorganic Cyclohexane-like Connectors with Stereochemically Tunable Exit Vectors for Molecular and Macromolecular Chemistry.

Robust organic molecules that place functional groups at well-defined angular and radial separations are valued as connectors in synthetic chemistry. Examples include rigid, polyvalent arenes and bicyclic compounds featuring strong C-C or C-H bonds. Non-aromatic rings like cyclohexane are rare in this context due to the challenge of stereochemical control over C-H functionalization.
