Tuning CO <sub>2</sub> uptake capacity in covalent organic frameworks <i>via</i> metal doping
Covalent organic framework (COF) structures have been synthesized and doped with Cu<sup>2+</sup>, Mn<sup>2+</sup>, and Zn<sup>2+</sup>. Incorporation of a phenol moiety increases metal doping capacity by 2-5% by mass, and results in increased CO<sub>2</sub> adsorption by as much as 40%, compared to undoped structures. Interestingly, gas uptake is improved even though the incorporation of cations in the pore lowers the overall surface area of the structures.
