Porphyrin and pyrene-based conjugated microporous polymer for efficient sequestration of CO2 and iodine and photosensitization for singlet oxygen generation

Abstract

A novel porphyrin and pyrene-based conjugated microporous polymer (Por-Py-CMP) was synthesized via Sonogashira–Hagihara cross coupling reaction. It exhibited a high Brunauer–Emmett–Teller specific surface area (1014 m² g⁻¹) and high pore volume (0.81 cm³ g⁻¹). Por-Py-CMP demonstrated an excellent capacity for capturing carbon dioxide (13.2 wt%) at 273 K and 1 bar, and an outstanding ability to uptake iodine. It also showed high efficiency for singlet oxygen generation.
