Coupling of Cobalt-Tetraphenylporphyrin Molecules in Copper Nitride Molecular Network
ORAL
Abstract
We have used low temperature scanning tunneling microscopy to study the interaction between individual cobalt-tetraphenylporphyrin molecules and a molecular copper nitride network. We demonstrated that the molecular Cu$_{3}$N-Cu(110) network promotes the decoupling of the porphiryn, allowing to visualize the molecular orbitals and vibronic states of the molecule, while keeping a strong coupling of the Co atom in the center of macrocycle with the substrate. The reverse behavior was observed when the molecule was sitting on the Cu(110) metallic surface. First principle calculations confirm the assembled position of the molecule on top of N atoms and the decoupling from the surface.
