Abstract

Williamson type ether reactions were utilized for a high yield reaction of 4-chloro-2,2:6,2-terpyridine with ,-dihydroxy-functionalized poly(ethylene oxide) and poly(oxytetramethylene)s to obtain bis(terpyridine)-terminated telechelics. The completeness of the functionalization was proven by NMR spectroscopy, GPC and MALDI-TOF-MS investigations. The addition of transition metal ions resulted in a polyaddition polymerization leading to the formation of extended metallo-supramolecular polymers, as proven by UV/VIS spectroscopy titration experiments.
