Route 4: Other

SI p001 · Synthesis of Ag5BHT films

Metal precursorsAg film converted to Ag2O film by plasma oxidation; example Ag2O thicknesses 50 or 100 nm

Linker precursorsH6BHT film deposited by thermal evaporation; H6BHT/Ag2O thickness ratio 1.3:1

Solventsisopropanol vapour

Atmosphereclosed container filled with an atmosphere containing vaporised isopropanol

Temperature90-120

Timeseveral days; about 48 h for 50 nm Ag2O/65 nm H6BHT and about 120 h for 100 nm Ag2O/130 nm H6BHT

Substrate orientationSi, Si/SiO2 wafer, or glass substrates; no crystallographic orientation specified

Oxidant / reductantPlasma oxidation converts Ag film to Ag2O; Ag2O reacts with H6BHT under isopropanol vapour

Work-upNo post-synthesis wash or activation reported for the films; black Ag2O/H6BHT films convert to shiny light-green Ag5BHT films.

Scalability contextThe method gives controllable 100-300 nm films and the authors describe uniform smooth films with lower energy demand; no explicit scale-up area is reported.
