Popis
Shrnutí:Based on cumulative research from the past two decades, this personal perspective defines the structurally unique features of Polymers of Intrinsic Microporosity (PIMs), which result in a distinct combination of properties, including solution-processability and microporosity, providing organic materials suitable for the fabrication of membranes that perform efficient molecular sieving. [Display omitted] •Personal reflection on the development of Polymers of Intrinsic Microporosity (PIMs).•Explanation of why PIMs form a distinct class of polymer and microporous material.•Re-definition of PIMs based on their method of synthesis, structure and properties.•Rigidity and sub-nanometre pore size combine to make PIM membranes selective.•Free volume is largely interconnected but only for the transport of small gases.
