Nonacene Generated by On-Surface Dehydrogenation
The
on-surface synthesis of nonacene has been accomplished by dehydrogenation
of an air-stable partially saturated precursor, which could be aromatized
by using a combined scanning tunneling and atomic force microscope
as well as by on-surface annealing. This transformation allowed the
in-detail analysis of the electronic properties of nonacene molecules
physisorbed on Au(111) by scanning tunneling spectroscopy measurements.
The spatial mapping of molecular orbitals was corroborated by density
functional theory calculations. Furthermore, the thermally induced
dehydrogenation uncovered the isomerization of intermediate dihydrononacene
species, which allowed for their in-depth structural and electronic
characterization
