Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Two 3D noninterpenetrating porous metal–organic frameworks (PMOFs) [Cd3(L1)2(DMA)2]·DMA [1, H3L1 = tris(p-carboxylic acid)tridurylborane] and [Zn3(L2)3(H2O)2]·5H2O·2EtOH [2, H2L2 = 4,4′-((2,3,5,6-tetramethylphenyl)boranediyl)bis(2,3,5,6-tetramethylbenzoic acid)] were synthesized by employment of a C3-symmetric ligand (H3L1) to assembly with Cd(NO3)2 or Zn(NO3)2. Complex 1 exhibits a (3, 6)-connected topological network based on a Cd3 cluster and Y-shaped trinodal organic linker. Complex 2 shows a 6-connected topology, since in situ decarboxylic reaction of the initial H3L1 occurred to generate a new ligand, H2L2, which can be considered as a linear linker. Both 1 and 2 exhibit blue fluorescence. Significantly, complex 1 with larger channels is unstable upon the removal of guest molecules. In contrast, activated 2 exhibits higher stability and permanent porosity.
