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=CF 3 SO 3 − ) that have different ligand‐exchange dynamics is used to cross‐link poly(4‐vinylpyridine).
