| Abstract Scope |
Metal−organic frameworks (MOFs) exhibit tremendous promise in sensing applications. However, the incorporation of MOFs onto sensing platforms such as optical fibers requires thin film growth techniques that are high-quality, scalable, and manufacturable. Here, a facile, rapid strategy to grow copper benzene-1,3,5-tricarboxylate (Cu−BTC) MOF thin films using the plasmonic substrate aluminum-doped zinc oxide (AZO) as a seed layer is demonstrated. The AZO templates Cu−BTC growth, with MOF formation only occurring on the AZO layer, allowing growth chemicals to be recycled. A dense Cu-BTC film is obtained within 10 minutes at room temperature, circumventing energy-intensive heating steps and long reaction times. We demonstrate that variables including the copper precursor anion, solvent conditions, and pH can systematically fine-tune both the packing density and size of the MOF crystals on AZO. The technique described here is rapid and applicable to a variety of substrates, providing a robust strategy for incorporating MOFs into sensing devices |
