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

Two rigid macrocyclic CTV-based porous organic polymers, Click-POP-1 and Click-POP-2, have been synthe- sized by Click reaction of a cyclotriveratrylene analogue with alkyne groups and aromatic azides in one pot. FTIR, solid 13C NMR and elemental analysis confirmed the formation of the polymers. Both of them possess high thermo-stability which is up to 410 and 900 ℃, 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 m2·g ^-1.
