Abstract

Self-assembled monolayers (SAMs) of 1,1′-biphenyl-4-thiol are patterned by using UV/ozone treatment through a shadow mask. After subsequent irradiation with low-energy electrons, the SAM is cross-linked to form a two-dimensional, holey nanosheet with a thickness of ∼1 nm. This nanosheet is mechanically stable and can be released from the original gold substrate and transferred to new substrates, including transmission electron microscopy (TEM) grids. The process is monitored by complementary microscopic techniques as well as X-ray photoelectron spectroscopy (XPS).
