Main-chain dynamics in metallo-supramolecular polymers: from solution to elastomeric fibres

Main-chain reversible coordination polymers were formed from bis-platinum pincer complexes 2 and bis-pyridine-terminated poly-THF-bis-Py 1. The properties of the polymers, both in solution and in fibres drawn from solution, are characterised. Structural perturbations that influence the ligand exchange (dissociation) rate of the defining metal–ligand bond have no measurable impact on either the viscosity of the polymer solutions or the ultimate yield behaviour of the fibres.
