Abstract: Porous compositions such as flexible polymers with side chain porosity are generally provided. In some embodiments, the composition comprises a flexible polymer backbone and a plurality of rigid side chains. In some embodiments, the rigid side chains form pores. In some embodiments, the rigid side chains may comprise two or more [2.2.2] bicyclic cores (e.g., formed by a ring opening metathesis polymerization. The compounds and methods described herein may be useful in various applications including, for example, gas separation.
