Novel Functionalized Metal-Organic Framework Based on Unique Hexagonal Prismatic Clusters

The novel porous 3D metal-organic framework synthesized from fluorenone-2,7-dicarboxylate contains zinc-glycolate carboxylate layers in which the unique hexagonal prismatic [Zn-6(OCH2CH2O)(6)] clusters are connected by planar [Zn-3(OCH2CH2O)(COO)(2)] motifs; the pore surface is furnished with carbonyl groups and open metal sites.
