Porous organic polymers with spiro-thioketal linkages for effective iodine capture

The thiol-aldehyde polycondensation reaction was employed to synthesize novel spiro-thioketal-based porous organic polymers. At 75 °C, iodine uptake capacities of POPSPs were measured as 4.13, 5.25, and 5.65 g g −1 , respectively.
