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.
