Polymers having intrinsic microporosity including sub-units with troger's base and spirobisindane moieties

摘要

A polymer comprising a sub-unit or repeating unit including a spirobisindane moiety and Troger's base moiety linked together by way of a linking group (L) wherein the linking group (L) is represented by Formula III:; wherein Z and Z′ are independently selected from an ether and ester functional group.
