Chiral self-assembled molecular networks are important both for technological and fundamental reasons. In spite of the large number of works in this field, the subtle mechanism of chirality transfer from single molecules to large scale two-dimensional (2D) networks is not well understood yet. This work reports on the self-assembly of simple amino alcohols on Cu(100) with different chirality measure; ethanolamine, alaninol (2-amino-1-propanol) and butanolamine (2-amino-1-butanol) have been investigated with scanning tunneling microscopy (STM), low-energy electron diffraction (LEED) and photoelectron spectroscopy (PES), corroborated with density functional theory (DFT) calculations. This systematic study addresses the role of the single-molecule handedness in the global chirality expression, indicating that the chirality measure of the precursors is an important variable for the formation of globally chiral superstructures.
