摘要：

The rate and extent of aqueous metal ion transport (Ag+, Au+3, Cu+2, Eu+2, Eu+3, Fe+2, Fe+3, Gd+3, Ni+2, Pd+2, Pt+2, and Pt+4) into microphase-separated block copolymers of methyl-tetracyclododecene (MTD) and 2-norbornene-5,6,-dicarboxylic acid (NORCOOH) was monitored using inductively coupled plasma atomic emission spectroscopy. Continuous interconnected polyNORCOOH domains were found to be necessary for metal ion uptake. The metal-bound carboxylate ions in the polyNORCOOH domains can be re-protonated by hydrogen reduction, rendering them active for further participation in metal binding. Following reduction, metal nanocluster-containing films were characterized using wide-angle X-ray scattering, infrared spectroscopy, and ultraviolet-visible spectroscopy.
