"Synthesis of an Isocyanate-Functionalized Terpyridine as Building Block for Metallo-Supramolecular Polymers";
An amino-pentyl-functionalized terpyridine was converted to the corresponding isocyanate, which could be crystd. 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-titrn. proved successful functionalization and complexation. Secondly, the isocyanate building block was successfully utilized for the formation of a metal coordinating compd. with two different binding moieties as was proven by 1H NMR spectroscopy.
