MICROPOROUS POLYMER MATERIAL

摘要

A microporous material comprises organic macromolecules comprised of first generally planar species connected by rigid linkers having a point of contortion such that two adjacent first planar specifies connected by the linker are held in non-coplanar orientation, subject to the proviso that the first species are other than porphyrinic macrocycles. Materials in accordance with the invention have a surface area of at least 300 m 2 g -1 , eg in the range 700-1500 m 2 g -1 . Preferred points of contortion are spiro groups, bridged ring moieties are sterically congested single covalent bonds around which there is restricted rotation.
