Intrinsically microporous polyimides derived from norbornane-2-spiro-α-cyclopentanone-α′-spiro-2″-norbornane-5,5″,6,6″-tetracarboxylic dianhydride

Here, a series of intrinsically microporous polyimides (PIM-PIs) were prepared from norbornane-2-spiro-α-cyclopentanone-α′-spiro-2″-norbornane-5,5″,6,6″-tetracarboxylic dianhydride (CpODA) and archetypal contorted diamines, and their microstructures and gas transport properties were systematically i...
