Rational design and synthesis of a porous, task-specific polycarbazole for efficient CO2 capture

We present a rational design and synthesis of a novel porous pyridine-functionalized polycarbazole for efficient CO2 capture based on the density functional theory calculations. The task-specific polymer, generated through a one-step FeCl3-catalyzed oxidative coupling reaction, exhibits a superior CO2 uptake at 1.0 bar and 273 K (5.57 mmol g(-1)).
