Problems solved by technology

So far, for porous organic polymers, most of the nitrogen-containing Lewis base coordination groups exist in the form of mono- or bidentate-coordinated nitrogen-containing groups, such as pyridine, 1,3,5-triazine, 2,2-bipyridine, etc. These coordination sites are not very stable for transition metal ions, and can only be coordinated for specific transition metal ions, so they are not universal
In contrast, nitrogen-containing tridentate ligands have a stronger ability to coordinate with transition metal ions, for example, 2,2′:6′,2″-terpyridine can coordinate with most transition metal ions, while Such porous organic polymers modified with tridentate nitrogen-containing Lewis base coordination groups are rarely reported
