Abstract

Highly crystalline Fe-COFs were constructed from the building blocks carrying pyridyl-aldehyde and triamine moieties in the presence of Fe(OTf)₂ and acetic acid under ambient conditions via a subcomponent assembly strategy. The spectral results prove the coordination of atomically distributed Fe(II) ions with the nitrogen species of covalently formed iminopyridine linkages.
