Synthesis and Properties of Porous Organic Polymers from a Rigid Macrocyclic Building Block

Abstract Two rigid macrocyclic CTV‐based porous organic polymers, Click‐POP‐1 and Click‐POP‐2, have been synthesized by Click reaction of a cyclotriveratrylene analogue with alkyne groups and aromatic azides in one pot. FTIR, solid 13 C NMR and elemental analysis confirmed the formation of the polymers. Both of them possess high thermo‐stability which is up to 410 and 900°C, respectively, and moderate hydrogen storage properties with 0.46 wt% at 77 K. Their nitrogen uptake showed type‐I isotherm with BET surface areas up to 342 and 317 m 2 ·g −1 .
