This lecture will detail our latest results in the formation of porous polymers using selected bicyclic building blocks. We originated the use of triptycene and related materials to give materials to give high degrees of free volume 20 years ago and this approach has proven to be a robust design. As a result, we continue to examine these types of materials in pursuit of advanced materials. New routes to functional triptycene containing poly(ether ether ketone)s PEEKs and poly(ether sulfone)s will be reported and their use as membrane materials. We will also report on the use of rigid macromonomers having a combination of [2.2.2] and [2.2.1] ring systems to create high surface area materials. In this case the conversion of the macromonomer to a pendant side chain polymer gives rise to a large increase in free volume and surface area as determined by BET measurements. The later methods are robust and significant fractions of comonomers can added into the polymer, while maintaining the high surface area. The utility of these materials as absorbents and as separation materials will be detailed.
