abstract = {Functionalized naphthalene diimides (NDIs) are attractive
candidates as small molecule acceptors for various molecular
electronic applications due to their reversible two-step
one-electron reductions at relatively low potentials. Here,
we utilize low-temperature scanning tunneling microscopy
(STM) to study the spatial extent and the electronic
structure of 2,7-dibenzyl 1,4,5,8-naphthalenetetracarboxylic
diimide (BNTCDI) adsorbed on the Pt(111) surface. We
succeeded to map in real space the electronic structure of
this three-dimensional (3D) molecule with orbital
resolution, and thus were able to image an in-plane π-nodal
plane located at the benzyl side arms. Furthermore, on the
basis of the comparison of voltage dependent STM images and
ab initio density functional theory simulations, we are able
to explain the STM features of BNTCDI in terms of a
convolution between its 3D shape and electronic structure.
Importantly, for this weakly coupled molecule on the Pt(111)
substrate, the intramolecular N···H–C hydrogen bonds
(i) stabilize the protruding π-systems of the benzyl groups
perpendicular to the flat NDI core and (ii) open an
effective transport path around Fermi energy.},
