Reversible coordination and facilitated transport of molecular nitrogen in poly((vinylcyclopentadienyl)manganese) membrane

Kinetic and equilibrium constants of nitrogen coordination to cyclopentadienylmanganese (CpMn) are spectroscopically determined by using the membrane of the copolymer of (vinylmethylcyclopentadienyl)dicarbonylmanganese and octyl methacrylate. Nitrogen transport through the membrane is selectively augmented due to the rapid and reversible coordination of nitrogen to the fixed CpMn. The facilitated nitrogen-transport behavior is in accordance with a dual-mode transport model to give diffusion coefficients of the penetrant.
