| Outline of Final Research Achievements |
In this project, we deposited meso-dibenzoporphycene (mDBPc) molecules on silver, lead and copper substrates and studied these systems with intra-molecular resolution atomic force microscopy and scanning tunneling microscopy using functionalized probes with a carbon monoxide molecule attached to the forefront part of the probe apex. We wanted to characterize the cis- and trans- configurations predicted for the mDBPc molecule upon adsorption on the above mentioned surfaces and study the influence of the local environment on the tautomerization reaction. Our experiments point towards a complex energy adsorption landscape of the mDBPc molecule where one of the configurations has a clear dominant energy potential well with respect to the other, and an adsorption position displaying the cis or trans form as the most stable adsorption configuration seems to depend on the nature of the substrate, through the interaction of the unsaturated nitrogen atoms of the molecule with it.
