Highly efficient and reversible iodine capture using a metalloporphyrin-based conjugated microporous polymer

Abstract

A new metalloporphyrin-based conjugated microporous polymer, NiP-CMP, was constructed via a homo-coupling polymerization reaction. NiP-CMP possesses a high BET surface area of over 2600 m² g⁻¹, a large pore volume of 2.288 cm³ g⁻¹, good stability, and displays excellent guest uptake of 202 wt% in iodine vapour. We also highlight that the polymer exhibits outstanding performance for the reversible adsorption of iodine in solution.
