Synthesis of a phthalocyanine and porphyrin 2D covalent organic framework

A new phthalocyanine and porphyrin based hybrid covalent organic framework, CoPc-PorDBA COF, has been synthesized and its gas storage properties have been measured. The CoPc-PorDBA COF crystallizes into 2D sheets with an eclipsed AA stacking motif, and it showed high surface area (SBET = 1315 m2 g−1), and can store up to 0.8 wt% of H2 at 77 K and 1 bar and 0.6 wt% of CH4 at 298 K and 1 bar.
