Terpyridine Modified PVC: Possibilities for Supramolecular Grafting and Cross-linking
-
Meier, Michael; Schubert, Ulrich S.
- Abstract:
- Commercially available poly(vinyl chloride) (PVC) was covalently modified
with terpyridine supramolecular binding units in a two-step reaction. First, PVC was
modified with aromatic thiols to introduce OH functionalities into the polymer backbone,
which were subsequently reacted with an isocyanate-functionalized terpyridine
binding unit. The resulting functionalized material contained metal-ion binding sites,
which could be used for grafting and crosslinking reactions. A grafting experiment was
performed with a small organic terpyridine ligand. The complexation of the modified
PVC with several transition-metal ions was studied with ultraviolet–visible spectroscopy
and gel permeation chromatography.
