Data for Electric field-controlled synthesis and characterisation of single metal-organic-framework (MOF) nanoparticles Peter D. J. Morris (24947014) Ian J. McPherson (1775896) Martin A.

Unwin (1298697) Electrochemistry Metal-organic frameworks Nanoparticles Migrated from ePrints Achieving control over the size distribution of metal organic framework (MOF) nanoparticles is key to biomedical applications and seeding techniques. Electrochemical control over the nanoparticle synthesis of the MOF, HKUST‐1, is achieved using a nanopipette injection method to locally mix Cu 2+ salt precursor and benzene tricarboxylate (BTC 3‐ ) ligand reagents, form MOF nanocrystals, and collect and characterise them on a TEM grid. In situ analysis of the size and translocation frequency of HKUST‐1 nanoparticles is demonstrated, using the nanopipette to detect resistive pulses as nanoparticles form. Complementary modelling of mass transport in the electric field, enables particle size to be estimated and explains the feasibility of particular reaction conditions, including inhibitory effects of excess BTC 3‐ . These new methods should be applicable to a variety of MOFs, and scaling up synthesis possible via arrays of nanoscale reaction centres, for example using nanopore membranes.<br><br>Data record consists of a zip archive, containing 8 subfolders organised according to data contained, and accompanying readme file. Data is electrochemical transient data in ASCII Text File. Each line of the data represents the elapsed time (in seconds) and the synchronously recorded current (in nA) from three nanopipettes, separated by commas. The concentration of H3BTC is given in the filename, the remaining details are found in the supporting information. 2020-06-07T00:00:00Z Dataset Dataset 10.82444/warw.33808606.v1 https://figshare.com/articles/dataset/Data_for_Electric_field-controlled_synthesis_and_characterisation_of_single_metal-organic-framework_MOF_nanoparticles/33808606 CC BY 4.0
