Abstract
The present invention provides for novel solid state O2-selective metal complex-based adsorbents and their utility for separating oxygen from a gas stream. In particular, the invention provides for an adsorption complex which contains four-coordinate O2-selective metal complexes including oligomeric/polymeric metal complexes, and organic base-containing polymers supported on porous materials.
