Rational synthesis and characterization of porous Cu(ii) coordination polymers

Porous coordination polymers or metal–organic frameworks constructed from metal ions and organic ligands have attracted much attention as next-generation porous materials due to their high designability, regularity, flexibility, and porosity. In particular, the Cu(II) ion with Jahn–Teller distortion can offer unique functions (coordination flexibility, Lewis acid property, and polarity) to porous frameworks. In this Perspective, we focus on porous Cu(II) coordination polymers; their unique characteristics and potential future applications are illustrated by recent experimental results.
