“…In contrast, strong adsorbatesubstrate interactions are often accompanied by a transfer of electron density, which in most cases means transfer of negative charge from the substrate to the phthalocyanine (cf. Section 5) [194]. The resulting dipole moments along the surface normal are parallel and induce repulsive intermolecular interactions.…”

“…Self-assembly of phthalocyanines is driven by intermolecular interactions, which can be attractive or repulsive, depending on the molecular structure and the character of the surface chemical bond. The frequently observed chemisorptive interactions facilitate electron transfer between substrate and adsorbate [194], and the resulting dipoles along the surface normal are repulsive and can over-compensate the lateral van der Waals attraction (cf. Section 5).…”

“…Another important contribution to the adsorbate-substrate bond results from the physisorptive and chemisorptive interactions of the ligand with the surface. The chemisorptive contributions can be accompanied by electron transfer [194] and influence the electronic, structural [197,341] and magnetic [542,543] properties of the complex, while the van der Waals attraction between ligand and substrate can lead to adsorption-induced deformation, especially in the case of porphyrins (cf. Section 4.…”

“…The electronic structure of adsorbed porphyrins and phthalocyanines, the details of their chemical bonding to metal substrates, and influences of the substrate on the chemical and magnetic properties of the coordinated metal centers have been subject to extensive investigation [9,20,21,194]. Motivated by the prospects of using porphyrin and phthalocyanine complexes in molecular organic electronics [83,537,538] or spintronics [539], phenomena such as the energy level alignment [540], the interfacial electronic structure [9,20,194] and the interface-related magnetic properties [21] have been studied for numerous metal/organic and organic/organic interfaces involving metalloporphyrins and -phthalocyanines.…”

It is shown that the self‐assembly of a surface‐confined metal–organic network such as cobalt porphyrins on graphene is accompanied by the evolution of coordination‐dependent observables in the electronic structure: variation of the layer's valence states within almost 1 eV range and of the metal atoms oxidation states. Coordination of cobalt porphyrins, driven by Co ad‐atoms, allows the synthesis of single metal atom centers with +3, +2, or +1 oxidation states. The electronic structure is determined by lateral interactions extending up to a few nanometers, beyond nearest‐neighbor distances. The reactivity of the single Co sites, which is strongly dependent on the local electronic configuration and, thus, on the metal‐specific oxidation state, is probed by carbon monoxide, which is found to ligate at pyridinic Co(I) at room temperature for background pressures above a fraction of a mbar.

The use of molecular materials in solar cells and nano‐electronics demands a fundamental understanding and control of their electronic properties. Particularly relevant is the molecular response to the environment, that is, the interaction with the support and adjacent molecules, as well as the influence of electrostatic gating. Here, the control of molecular level alignment and charge states of fluorinated cobalt phthalocyanines (F16CoPc) on atomically thin hexagonal boron nitride (h‐BN) sheets on Cu(111) is reported using scanning tunneling microscopy (STM) and spectroscopy (STS), as well as atomic force microscopy (AFM) and complementary density functional theory (DFT) calculations. Three parameters that govern the electronic level alignment of F16CoPc orbitals are investigated: i) template‐induced gating by the work function variation of the h‐BN/Cu(111) substrate, ii) gating by the STM tip, and iii) screening by neighboring molecules. The interplay of these parameters influences the charge distribution in the studied molecular arrangements and thus provides the possibility to tune their physicochemical behavior, for instance, the response toward electronic or optical excitation, charge transport, or binding of axial adducts.
