This presentation will introduce the design and synthesis of structurally new

monomers and their polymerization to form rigid ladder polymers, resulting in

polymers of intrinsic microporosity (PIM) having high molecular weights. The

structures of the PIMs have a strong influence on gas permeability. Gas

permeability and selectivity can be tuned by the size of the pendant substituent

and the spacing between contorted centers in the chain, because of changes in

the polymer chain packing or d-spacing. The new PIM series were more selective

to all gases/nitrogen compared with PIM-1, the most commonly reported PIM

structure having high molecular weight.
