Content matters: The reaction of polycyclooctadiene (Poly(COD)) and [{RhCl(C2H4)2}2] produced well-defined π-bound hybrid polymers, the size of which depended on rhodium content (see picture). The reaction of these polymers with a phosphine aldehyde led to the regeneration of the original polymers, thus proving the accessibility of the metal.
