Synthesis of a Polyimide Porous Porphyrin Polymer for Selective CO2 Capture

Abstract EN

A new microporous porphyrin-based imide linked polymer, PyP, was synthesized in an m-cresol/isoquinoline mixture between a porphyrin and a naphthalene tetra-carboxylic dianhydride.

The resultant amorphous polymer demonstrates a moderate surface area (SBET = 428 m2 g−1) and CO2 adsorption ability (3.5 wt%) and a CO2/CH4 selectivity of 5.6 at 273 K/1 bar.
