Metalation of a Mesoporous Three-Dimensional Covalent Organic Framework

Constructing metalated three-dimensional (3D) covalent organic frameworks is a challenging synthetic task.

Description
Summary:Constructing metalated three-dimensional (3D) covalent organic frameworks is a challenging synthetic task. Herein, we report the synthesis and characterization of a highly porous (SABET = 5083 m2 g–1) 3D COF with a record low density (0.13 g cm–3) containing π-electron conjugated dehydro­benzo­annulene (DBA) units. Metalation of DBA-3D-COF 1 with Ni to produce Ni-DBA-3D-COF results in a minimal reduction in the surface area (SABET = 4763 m2 g–1) of the material due to the incorporation of the metal within the cavity of the DBA units, and retention of crystallinity. Both 3D DBA-COFs also display great uptake capacities for ethane and ethylene gas.
