DRMs: 1-butanol, ethanl and air to obtain C\_Par and K\_Cell - linker precursor solution as a function of the growth cycle (1-200) - spectra were recorded after the 300, 600 and 900 seconds after the initial exposure to the linker solution, only the 900 s data was evaluated - single frequency impedance data was recorded during the initial 300 seconds of the linker solution exposure step at 100 kHz - metal precursor solution as a function of the growth cycle (1-200) - spectra were recorded after 200, 400 and 600 seconds after initial exposure to the metal solution, only the 600 s data was evaluated - single frequency impedance data was recorded during the initial 200 seconds of the metal solution exposure step at 100 kHz - testing solutions as a function of the growth cycle - spectra were recorded after 180, 240 and 300 seconds after initial exposure to the respective testing solution, only the 300 s data was evaluated - single frequency impedance data was recorded during the initial 180 seconds of each testing solution exposure step at 1 MHz - ECM 2 fit results to the metal and linker data copied into the excel file "Growth\_Data\_BatchFit\_Results.xlsx" - ECM 1 fit results to the testing solution spectra recorded before the HKUST-1 coating process copied into the excel file "Cycle\_0\_DataFits.xlsx" - ECM 2 fit results to the testing solution spectra recorded with the HKUST-1 coated electrode structure copied into the excel files "Cycle\_50DataFits.xlsx", "Cycle\_100\_Data\_Fits.xlsx", "Cycle 150 Data Fits.xlsx" and "Cycle\_200DataFits.xlsx", -
