Abstract

The synthesis of a new porous organic polymer that features high surface area and pores of appropriate size and composition to capture CO 2 from mixtures with methane, was reported. The desired micro-and ultramicro-porosity was engendered by using a tetrahedral building block that is expected to produce a three-dimensional network. Single component adsorption isotherms for CO 2 and CH 4 were measured volumetrically for diimide subunits heated under a vacuum at 160°C. The selectivities for CO 2 CH 4 mixtures were calculated using ideal adsorbed solution theory (IAST). The first of these new materials, simply made from inexpensive precursors, shows outstanding thermal and chemical stability, and exceptional promise for CO 2 CH 4 separation.
