2 · Fabrication of oriented Cu3(BTC)2 patterns

Metal precursorsoriented Cu(OH)2 thin film deposited onto photoresist-patterned Si wafer

Linker precursorsH3BTC conversion solution as in route_oriented_cu_btc_film

Solvents2-propanol development; acetone sonication/wash; ethanol-water conversion solution

AdditivesEco UV Resin photoresist; Cr photomask

Atmosphereair drying; reaction atmosphere not specified

Temperatureroom temperature for Cu3(BTC)2 conversion

Timephotoresist spin coat 40 s; UV exposure 15 s; acetone sonication 10 min; Cu3(BTC)2 conversion 10 min

Substrate orientationSi wafer; patterned oriented Cu(OH)2 film with nanobelt a-axis aligned horizontally in images

Work-upphotoresist removed by acetone sonication, washed with acetone, dried under air, then converted using the Cu3(BTC)2 film procedure

Scalability contextMicrometre-scale patterns were demonstrated; authors state resolution up to 50 nm may be possible because Cu(OH)2 nanobelt width is ~50 nm.
