ABSTRACT:
The present invention relates to a microporous material which is a non-network polymer having a chain comprised of repeating units bonded to each other and each including a first generally planar species and a rigid linker, the linker having a point of contortion such that two adjacent first planar species connected by a rigid linker are held in a non-coplanar orientation, the rigid linker further being such that the polymer chain has a rigid contorted structure, and the polymer being such that said repeating units comprised of the first generally planar species and the rigid linker are bonded predominately to two other such repeating units.
