Dioxouranium(VI) Dicarboxylate Polymers: Synthesis and Characterization of Tractable Coordination Polymers and Evidence for Rigid Rod Confirmation.

Abstract

A series of polymeric dicarboxylato dioxouranium (VI) species have been synthesized via an equilibrium controlled solution reaction where bis(acetato)dioxouranium (VI) dihydrate undergoes an acid interchange with a dicarboxylic acid. The solution synthesized species have number average molecular weights of up to 1.8 x 10 to the 4th power based on end group analysis, gel permeation chromatography, inherent viscosity and elemental analysis. The empirical Mark-Houwink relation of viscosity to molecular weight has been demonstrated for poly(3,3-dimethyl-pentanedionato)(dimethyl sulfoxide) dioxouranium (VI) which is indicative of rigid rod conformation. This series has also been prepared interfacially where the disodium salt of a dicarboxylic acid in an aqueous phase reacted with bis(nitrato)dioxouranium (VI) hexahydrate in diethyl ether. Keywords: Polymers, Uranium, Carboxylic acids, Diuranyl, Metal-containing polymers.
