Реферат:
Two-dimensional metal-organic frameworks (MOFs) occupy a special place
among the large family of functional 2D materials. Even at a monolayer level,
2D MOFs exhibit unique sensing, separation, catalytic, electronic, and
conductive properties due to the combination of porosity and
organo-inorganic nature. However, lab-to-fab transfer for 2D MOF layers faces
the challenge of their scalability, limited by weak interactions between the
organic and inorganic building blocks. Here, comparing three top-down
approaches to fabricate 2D MOF layers (sonication, freeze-thaw, and
mechanical exfoliation), The technological criteria have established for
creation of the layers of the thickness up to 1 nm with a record aspect ratio up
to 2*10ˆ4:1. The freezing-thaw and mechanical exfoliation are the most
optimal approaches; wherein the rate and manufacturability of the mechanical
exfoliation rivaling the greatest scalability of 2D MOF layers obtained by
freezing-thaw (21300:1 vs 1330:1 aspect ratio), leaving the sonication
approach behind (with a record 900:1 aspect ratio) have discovered. The high
quality 2D MOF layers with a record aspect ratio demonstrate unique optical
sensitivity to solvents of a varied polarity, which opens the way to fabricate
scalable and freestanding 2D MOF-based atomically thin chemo-optical
sensors by industry-oriented approach.
