Strong Means Slow: Dynamic Contributions to the Bulk Mechanical Properties of Supramolecular Networks

Hold on tight: The dynamics, rather than thermodynamics, of reversible cross‐links are the primary determinants of bulk viscosities in a family of supramolecular networks. This result comes from a study in which a series of structurally similar pincer complexes (see picture, OTf=CF3SO3−) that have d...

Zusammenfassung:Hold on tight: The dynamics, rather than thermodynamics, of reversible cross‐links are the primary determinants of bulk viscosities in a family of supramolecular networks. This result comes from a study in which a series of structurally similar pincer complexes (see picture, OTf=CF3SO3−) that have different ligand‐exchange dynamics is used to cross‐link poly(4‐vinylpyridine).
