Polymers of Intrinsic Microporosity Derived from Bis(phenazyl) Monomers

Abstract

Novel polymers of intrinsic microporosity (PIMs) are prepared from bis(phenazyl) monomers derived from readily available bis(catechol)s. One of the polymers (termed PIM-7) has an excellent combination of properties with high internal surface area, good film-forming characteristics, and gas transport properties that make it a suitable candidate for gas separation membranes. The high gas permeability and good ideal selectivity of PIM-7 place it above Robeson's upper-bound for a number of commercially important gas pairs (e.g., O2/N2, CO2/CH4, and CO2/N2).
