A New 2D Porous Pb-MOF Based on Ribbon‐Shaped SBU and 2-Nitroimidazole: Structure and Properties

A new porous metal-organic framework, [Pb 5 (OAc) 7 (nIm) 3 ] n ( 1 ), has been successfully synthesized by employing 2-nitroimidazole ligand and Pb 2+ ion. 1 contains novel the ribbon-shaped Pb-O SBU and reveals a 2D porous framework with a 1D tubular channel. Due to the existence of the electronegative O atom of nitro group and Lewis acid metal ion in the channel, 1 shows moderate CO 2 adsorption uptake of 25.8 cm 3 cm − 1 at 298 K and 760 mmHg, and adsorption sites are also confirmed by GCMC simulations. Moreover, the electronic structures and luminescence properties of 1 was investigated. This work displays an effective approach to enrich multifunctional porous Pb-MOFs.
