AbstractIn order to obtain linear and high molecular weight Ru(II) coordination polymers, we investigated the reaction conditions for the direct one-step metallopolymerization of bis-terpyridine poly(ethylene glycol) 3 with RuCl3 in the presence of reducing agents. Here we discuss the direct synthesis method, the optimization and the purification of the water soluble Ru(II) chain extended poly(ethylene glycol). The optimization of the metallo-polymerization was monitored by SEC. For the highest molecular weight Ru(II) coordination polymer 4 obtained in this study, full characterization was performed by 1H-NMR and UV-Vis spectroscopy as well as SEC proof for the formation and the stability of the designed structure

Electrorheological Properties

The self-assembly properties and ER effects of the Polyaniline-Poly(ethylene glycol)-Polyaniline (PAn-PEG-PAn) triblock copolymers were studied in this paper. The results indicate that with the increase of solubility parameter of the solvent, PAn-PEG-PAn copolymers form into different morphologies of spheriods, vesicles and rods. PAn-PEG-PAn copolymers with vesicles morphology show the highest polarization strength, while those with rods have the most rapid polarization rate. Among the PAn-PEG-PAn copolymers of different morphologies, the PAn-PEG-PAn copolymer vesicles show the strongest ER effect.
