A <i>C</i>₃‐Symmetric Macrocycle‐Based, Hydrogen‐Bonded, Multiporous Hexagonal Network as a Motif of Porous Molecular Crystals

Abstract

A C3-symmetric π-conjugated macrocycle combined with an appropriate hydrogen bonding module (phenylene triangle) allowed the construction of crystalline supramolecular frameworks with a cavity volume of up to 58%. The frameworks were obtained through non-interpenetrated stacking of a hexagonal sheet possessing three kinds of pores with different sizes and shapes. The activated porous material absorbed CO2 up to 96 cm(3) g(-1) at 195 K under 1 atm.
