Processing oriented metal-organic frameworks (MOFs) as thin films is a key challenge to for their application to device fabrication. However, typical fabrication methods cannot generate precisely oriented crystals on commercially relevant scales (i.e. cm2). This limits access to applications that require anisotropic functional properties (e.g. separation, optics, and electronics). Recently, highly oriented copper-based MOFs have been synthesized via the addition of the organic MOF component to an ethanolic solution of manually aligned Cu(OH)2 nanobelt films. In this work we report the optimization of a semi-automatic method that affords a 100% yield of high quality ceramic films, at the cm scale, for the fabrication of precisely oriented MOF coatings. This improved fabrication protocol will facilitate the progress of heteroepitaxially grown MOFs for molecular separators and micro-opto-electronic devices.
