Abstract
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,-dicar☐ylic 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 car☐ylate 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.
