Because such a framework structure was unexpected from the geometry of the monomers and did not match previous depictions or definitions of 2D-COFs nor 3D-COFs, the researchers thought it would be ...

Porous organic crystals with superior properties as CO2 adsorbents were created ... Because such a framework structure was unexpected from the geometry of the monomers and did not match previous ...

The researchers initially expected a three-dimensional (3D) covalent organic framework (3D-COF) to form due to the tetrahedral monomer's geometry. They anticipated a granular solid structure resulting ...
