Polymers of Intrinsic Microporosity (PIMs) possess microporosity because they have rigid, contorted molecular structures that cannot pack efficiently. They can be prepared either as insoluble network materials or soluble polymers that may be precipitated from solution as powders or cast into a membrane form (e.g. PIM-1). Unlike common microporous materials (e.g. activated carbons, zeolites) it is straightforward to tailor the chemical nature of PIMs to design materials for chemoselective processes. The unique structure and processability of PIMs makes them attractive for a number of applications including heterogeneous catalysis, gas separation membranes, water purification and hydrogen storage. The potential diversity of structure, as controlled by the choice of monomer, will allow the synthesis of PIMs specifically designed for each application. This talk will discuss some of the synthetic aspects behind PIM technology including the occurrence of branching and cyclic oligomer formation, scale-up considerations and novel monomer synthesis.
