    讲座摘要:

    Inthe pursuit of unusual ladder-shaped (macro)molecular structures with uniqueproperties, we developed Catalytic Arene-Norbornene AnnuLation (CANAL) tosynthesize rigid ladder polymers from readily available norbornenes and arylbromides. Efficient CANAL polymerization produced ladder polymers withmolecular weights up to 1 MDa, various functionalities, and contortedconformations, despite the formed strained ring in each repeat unit. Theseladder polymers exhibited high surface areas, high microporosity (pore width< 1 nm), and surprisingly high thermal stability up to 400 C withoutdetectable Tg. Membranes were fabricated as promising materials for gasseparations and understanding gas transport in glassy polymers.
