AB Dibenzomethanopentacene (DBMP) is shown to be a useful structural component for makingPolymers of Intrinsic Microporosity (PIMs) with promise for making efficient membranes for gas separations. DBMP-based monomers for PIMs are readily prepared using a Diels–Alder reaction between 2,3-dimethoxyanthracene and norbornadiene as the key synthetic step. Compared to date for the archetypal PIM-1, the  incorporation of DBMP simultaneously enhances both gas permeability and the ideal selectivity for one gas over another. Hence, both ideal and mixed gas permeabilitydata for DBMP-rich co-polymers and an amidoxime modified PIM are close to the current Robesonupper bounds, which define the state-of-the-art for the trade-off between permeability and selectivity, forseveral important gas pairs. Furthermore, long-term studies (over 3 years) reveal that the reduction in gaspermeabilities on ageing is less for DBMP-containing PIMs relative to that for other high performing PIMs,which is an attractive property for the fabrication of membranes for efficient gas separations.
