Synthesis of Two Triarylboron-Functionalized Metal–Organic Frameworks: In Situ Decarboxylic Reaction, Structure, Photoluminescence, and Gas Adsorption Properties WangXiaoqing YangJie ZhangLiangliang LiuFuling DaiFangna SunDaofeng 2014 Two 3D noninterpenetrating porous metal–organic frameworks (PMOFs) [Cd<sub>3</sub>(<b>L</b><sup>1</sup>)<sub>2</sub>­(DMA)<sub>2</sub>]·DMA [<b>1</b>, H<sub>3</sub><b>L</b><sup>1</sup> = tris­(p-carboxylic acid)­tridurylborane] and [Zn<sub>3</sub>(<b>L</b><sup>2</sup>)<sub>3</sub>­(H<sub>2</sub>O)<sub>2</sub>]·5H<sub>2</sub>O·2EtOH [<b>2</b>, H<sub>2</sub><b>L</b><sup>2</sup> = 4,4′-((2,3,5,6-tetramethylphenyl)­boranediyl)­bis­(2,3,5,6-tetramethylbenzoic acid)] were synthesized by employment of a <i>C</i><sub>3</sub>-symmetric ligand (H<sub>3</sub><b>L</b><sup>1</sup>) to assembly with Cd­(NO<sub>3</sub>)<sub>2</sub> or Zn­(NO<sub>3</sub>)<sub>2</sub>. Complex <b>1</b> exhibits a (3, 6)-connected topological network based on a Cd<sub>3</sub> cluster and Y-shaped trinodal organic linker. Complex <b>2</b> shows a 6-connected topology, since in situ decarboxylic reaction of the initial H<sub>3</sub><b>L</b><sup>1</sup> occurred to generate a new ligand, H<sub>2</sub><b>L</b><sup>2</sup>, which can be considered as a linear linker. Both <b>1</b> and <b>2</b> exhibit blue fluorescence. Significantly, complex <b>1</b> with larger channels is unstable upon the removal of guest molecules. In contrast, activated <b>2</b> exhibits higher stability and permanent porosity.
