We report the synthesis and characterization of a rhodium catalyst attached to a polymer which is designed to control catalyst reactivity in response to an applied stimulus. The catalyst precursor, Rh(Cl)(CO)2(NH2-polymer) was prepared from poly N-isopropylacrylamide (pNIPAAm) and Rh2(Cl)2(CO)4. The structure of the metal complex was interrogated using IR, UV/Vis, NMR and XAFS and catalytic activity was tested using an aqueous hydrogenation reaction.
