Control of Molecule–Metal Interaction by Hydrogen Manipulation in an Organic Molecule
Abstract
Free-base porphyrin molecules offer appealing options to tune the
interaction with their environment via the manipulation of their inner hydrogen atoms
and molecular conformation. Using scanning tunneling microscopy we show, through a
systematic study, that the molecular conformation, electronic gap, wave function, and
molecule−substrate interaction are modified by hydrogen switch or removal.
Experimental results in combination with ab initio calculations provide an understanding
of the underlying physical process.
