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 different ligand-exchange dynamics is used to cross-link poly (4-vinylpyridine).
