Solution-Processed, Organophilic Membrane Derived from a Polymer of Intrinsic Microporosity

A polymer with a rigid, randomly contorted molecular structure (see Figure), incorporating fused rings connected by spiro‐centres, may be precipitated or cast from solution to give microporous powders and membranes stable up to temperatures of 350 °C, with apparent surface areas > 600 m2 g–1.

Description
Summary:A polymer with a rigid, randomly contorted molecular structure (see Figure), incorporating fused rings connected by spiro‐centres, may be precipitated or cast from solution to give microporous powders and membranes stable up to temperatures of 350 °C, with apparent surface areas > 600 m2 g–1. Organophilic membranes may be formed, as demonstrated by the separation of phenol from water by pervaporation.
