p002 / 2 · Experimental, Device fabrication

Metal precursorsCopper(ii) nitrate hydrate; 5 mL Cu(NO3)2 aqueous solution, 5 mM
Linker precursorsBenzenehexathiol (BHT, 95%); 20 mL BHT ethyl acetate solution, 0.24 mM
SolventsDeionised water, acetone, alcohol, isopropanol, ethyl acetate; polyethylene glycol aqueous solution
AdditivesPolyethylene glycol (PEG, average Mn = 6000), 45 mL aqueous solution at 25 mg/mL
AtmosphereAmbient environment
Temperature60 deg C drying step; film growth at ambient temperature (not numerically specified)
Time0.5 h to observe transparent interfacial film; 24 h reaction before draining; substrate solvent-cleaning steps 30 min each; UV-ozone 30 min
Substrate orientationUV-treated glass substrate positioned at a certain height in a flow beaker, with liquid surface slightly above the glass substrate
Oxidant / reductantCu2+ and BHT redox during framework formation; authors state two equivalents of Cu2+ are reduced to Cu+ and BHT is oxidised to the -4 state
Work-upAfter 24 h aqueous and organic reaction solutions were drained, leaving Cu-BHT film on glass; films rinsed several times with ethyl acetate and deionised water.
ActivationNo activation reported; films used after rinsing and Ag electrode deposition.
Scalability contextAuthors describe large-area film preparation as a challenge and state this interfacial growth simplifies preparation; no scaled batch size beyond a 2 x 2 cm substrate is demonstrated.
