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

Abstract

Main-chain reversible coordination polymers were formed from bis-platinum pincer complexes 2 and bis-pyridineterminated 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.
