Abstract
  • PIMs are a class of ultra-permeable polymer that are attracting attention for membrane applications [1]. Here we describe the synthesis and properties of a new class of PIM prepared from aromatic diamine monomers using Tröger's base (TB) formation [2]. The choice of diamine monomer needs to conform to the design concept of PIMs to provide highly rigid and contorted structures, although the V-shaped bicyclic TB unit also introduces contortion in addition to providing strongly basic functionality. Several aromatic diamine monomers have been investigated as precursors and found to yield highly microporous polymers of sufficiently high molecular mass for film formation (e.g. Fig. 1). Gas permeability data for some of these polymer will be discussed. Figure 1. Examples of TB-PIMs. Acknowledgements: We thank the EPSRC and the EU FP7 programme DoubleNanoMem (NMP3-SL-2009-228631) for funding and the members of the DoubleNanoMem consortium for measurements of the properties of PIMs. References [1] N.B.
