Two new imine-linked covalent organic frameworks (NI-COF-1 and NI-COF-2) have been designed and conducted through Schiff base condensation reactions. NI-COFs displayed good porosity, stability, and crystallinity via the flexible units/fluorine...

The phenothiazine-based porous organic polymers (PTA-POPs) were constructed through a facile and cost-effective method. We used commercial phenothiazine as aromatic building units, formaldehyde dimethyl acetal (FDA) as a crosslinker under the catalysis of anhydrous FeCl 3 , which afford PTA-POPs with high yield. The phenothiazine-based porous organic polymers pos-sessed good porosity, excellent thermal stability, and rich heteroatom sites in the skeleton. Cationic PTA-POP (C-PTA-POP) was further synthesized via a simple process. Interestingly, the C-PTA-POP exhibited highly effective iodine vapor capture up to 3.69 g g À 1 , which is ranked the excellent performance among the reported POPs.
