Influence of Connectivity and Porosity on Ligand-Based Luminescence in Zinc Metal−Organic Frameworks

Abstract: Applications of metal-organic frameworks (MOFs) require close correlation between their structure and function. We describe the preparation and characterization of two zinc MOFs based on a flexible and emissive linker molecule, stilbene, which retains its luminescence within these solid materials. Reaction of trans-4,4'-stilbene dicarboxylic acid and zinc nitrate in N,N-dimethylformamide (DMF) yielded a dense 2-D network, 1, featuring zinc in both octahedral and tetrahedral coordination environments connected … Show more

“…[40] Intra-ligand based luminescence is typically observed with organic ligands that are highly conjugated, susceptible to π-stacking in the solid state. [40], [41] v. Fluorescent ligands can also be used in MOFs that are intended for biological applications, due to their ability to perform real-time measurements. [7], [42][43][44][45][46][47][48][49] For MOFs to be applicable for in vivo administration, the components of their framework should not intervene in the body's cycle, and ideally be excreted from the body.…”

“…These results indicate that MOF-5 prepared by solvothermal methods yields a higher purity phase with respect to ZnO contaminants and the PL data is in agreement with the ligand-centred emission found for an analogous cubic MOF containing stilbenedicarboxylate linkers. [101] Finally, fluorescence spectroscopy was also used to monitor MOF-5 degradation by water:…”

“…MOFs are a class of porous crystalline materials formed by the combination of transition metals or metal-containing clusters as structural nodes and organic compounds as linkers. With outstanding properties including high surface area, high pore volume, and flexibly tunable structure, MOFs were found to have a wide range of applications in gas adsorption [8,9], separation [10,11], chemical sensing devices [12], and catalysis [13]. Recently, MOFs have been discussed on its potential as a new class of photocatalysts such as MOF-5, isoreticular MOFs (IRMOF-1, IRMOF-2, IRMOF-7, IRMOF-8, IRMOF-9), MIL-53 (M = Al, Cr, Fe), UiO66 and UiO67 [14][15][16][17][18].…”
