| Abstract: | Rh6- monomer and polymer-immobilized complexes have been characterized using XPS and AFM. Polymer-immobilized clusters were obtained by the reaction of Rh6(CO)15CH3CN with copolymer of allyldiphenylphosphine and styrene. AFM study shows the change of surface morphology of the above copolymers. XPS data demonstrated the change of charge state of Rh atoms under monosubstitution of the CO-group for Rh6- monomer complexes as well as in copolymer cluster complexe after the catalysis process of hydrogenation. |
