报告摘要：
Intrinsic microporosity is defined as a continuous network of interconnected intermolecular microcavities, which is formed as a consequence of the contorted shape and chain rigidity of the polymer structure. The restricted chain rotation originating from sites of contortion or spiro centers leads to an inefficiently packed matrix with high free volume elements, typically above 20% FFV. ‘Polymers of Intrinsic Microporosity’ (PIMs) are high-free-volume microporous solvent-soluble polymers having rigid ladder-like structures incorporating contorted centers. With high surface areas, PIMs are considered as promising materials for membrane-based separations because of high product throughput or flux. In particular, they have been explored for non-aqueous nanofiltration (Imperial College) and more widely for gas separation, because of their very high gas permeability. In 2004, Budd and McKeown reported ‘PIM-1’ and other related structures, as a new class of high molecular weight microporous ladder polymer. Since the first published reports of PIM-1, the area of PIMs for gas separation has grown rapidly. Highlights of some of the speaker’s and several other researchers’ work on PIMs will be given, particularly on more recent work on a related class of microporous polyimides incorporating Tr?ger’s Base (TB), which is a rigid non-planar bridged bicyclic amine.
