Synthesis of an Isocyanate-Functionalized Terpyridine as Building Block for Metallo-Supramolecular Polymers

Hoogenboom, Richard; Andres, Philip R.; Kickelbick, Guido; Schubert, Ulrich S.

Abstract:

An amino-pentyl-functionalized terpyridine was converted to the corresponding isocyanate, which could be crystallized and studied by X-ray diffraction. The isocyanate-functionalized terpyridine was utilized as a reactive building block for the formation of a metal-coordinating polymer by reacting it under mild conditions with a hydroxy functionalized poly(THF). GPC characterization and UV-titration proved successful functionalization and complexation. Secondly, the isocyanate building block was successfully utilized for the formation of a metal coordinating compound with two different binding moieties as was proven by 1H NMR spectroscopy.
