Self-assembly patterning of organic molecules on a surface

摘要

The embodiments disclosed herein include all-electron control over a chemical attachment and the subsequent self-assembly of an organic molecule into a well-ordered three-dimensional monolayer on a metal surface. The ordering or assembly of the organic molecule may be through electron excitation. Hot-electron and hot-hole excitation enables tethering of the organic molecule to a metal substrate, such as an alkyne group to a gold surface. All-electron reactions may allow a direct control over the size and shape of the self-assembly, defect structures and the reverse process of molecular disassembly from single molecular level to mesoscopic scale.

主权项

1. A molecular monolayer self-assembly system comprising:
a substrate; an organic molecule layer disposed on the substrate; and an electron excitation source configured to generate an electron-induced reaction of the organic molecule layer that modifies a structure of the organic molecule layer between a flat lying disordered state and a three dimensional ordered state through tautomerization.
