One-pot synthesis of an ionic porous organic framework for metal-free catalytic CO2 fixation under ambient conditions

A new ionic porous organic framework (termed IPF-CSU-1) with a remarkably high nitrogen content (20.3 wt%), and a high-density and uniform charge distribution was constructed, which served as a metal-free catalyst for CO2 conversion into cyclic carbonates in high yields (above 95%) under an ambient condition (298 K, 0.1 MPa).
