Abstract
Hydrogen bonding is a vital driving force for organizing the hierarchy
molecular structure, especially in biologic field. Due to its
directionality, selectivity and moderate strength, hydrogen bonding has
been extensively introduced into the molecular recognition, sensing and
electronic devices. Electric meas-urements at single-molecule level
facilitate the investigation of hydrogen bonds and provide a
comprehensive understanding of the electron transport properties
governed by the hydrogen bonding, which is essential for the development
of self-assembled electronic systems. This review provides a de-tailed
overview of recent advancements in constructing single-molecule
junctions utilizing intramolecular and intermolecular hydrogen bonding.
We first introduce the methods utilized for characterizing the electric
and dynamic properties of non-covalent interactions. Next, we discuss
the mechanisms of electron transport, relevant influencing factors, and
typical applications utilizing electrical signals based on
single-molecule junctions. Finally, we propose our perspective on the
existing challenges and prospective opportunities in utilizing hydrogen
bonding for electronic device applications.27 Jun 20231st Revision Received 29 Jun 2023Submission Checks Completed
