Access to supramolecular polymers : large scale synthesis of 4'-chloro-2,2':6',2''-terpyridine and an application to poly(propylene oxide) telechelics

A new improved large scale synthesis of 4′-chloro-2,2′ : 6′,2′′-terpyridine is described in detail. Williamson type ether reactions were utilized for a high yield reaction of 4′-chloro-2,2′ : 6′,2′′-terpyridine with α,ω-bishydroxy-functionalized poly(propylene oxide). The completeness of the functionalization was proven by NMR, GPC and MALDI-TOF-MS investigations. The application of ruthenium(III)/(II) chemistry allowed then the construction of ABA type non-covalent architectures.

Linear coordination polymers: synthetic strategies and solution viscosities

Different synthetic strategies for the preparation of the coordination polymers [bis (2,2′:6′, 2′′-terpyridin-4′-yl)-FeCl2-di(ethylene glycol)]n, [bis (2,2′:6′,2′′-terpyridin-4′-yl)-Ru(BF4)2-di(ethyle glycol)]n, [bis (2,2′:6′,2′′-terpyrid-4′-yl)-FeCl2-poly(ethylene glycol)180]n and [bis (2,2′:6′,2′′terpyrid-4′-yl)-Ru(BF4)2-poly(ethylen glycol)180]n are reported. The influence of solvent, concentration and mode of metal ion addition is discussed on the basis of the observed solution viscosities.
