On-Surface Driven Formal Michael Addition Produces m-Polyaniline Oligomers on Pt(111) 2020 Access copy available to the general public Unrestricted On-surface synthesis is emerging as a highly rational bottom-up methodology for the synthesis of molecular structures that are unattainable or complex to obtain by wet chemistry. Here, oligomers of meta-polyaniline, a known ferromagnetic polymer, were synthesized from para-aminophenol building-blocks via an unexpected and highly specific on-surface formal 1, 4 Michael-type addition at the meta position, driven by the reduction of the aminophenol molecule. We rationalize this dehydrogenation and coupling reaction mechanism with a combination of in situ scanning tunneling and non-contact atomic force microscopies, high-resolution synchrotron-based X-ray photoemission spectroscopy and first-principles calculations. This study demonstrates the capability of surfaces to selectively modify local molecular conditions to redirect well-established synthetic routes, such as Michael coupling, towards the rational synthesis of new covalent nanostructures. info:eu-repo/grantAgreement/EC/FP7/610256/EU/Gas and Dust from the Stars to the Laboratory: Exploring the NanoCosmos/NANOCOSMOS info:eu-repo/grantAgreement/EC/H2020/785219/EU/Graphene Flagship Core Project 2/GrapheneCore2 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 785219-GrapheneCore2 info:eu-repo/grantAgreement/EC/H2020/881603/EU/Graphene Flagship Core Project 3/GrapheneCore3 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 881603-GrapheneCore3 info:eu-repo/grantAgreement/ES/MINECO/MAT2017-85089-C2-1-R info:eu-repo/grantAgreement/ES/MINECO/RYC-2015-17730 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 15.336 2020 CHEMISTRY, MULTIDISCIPLINARY 16 / 178 = 0.09 2020 Q1 T1 5.831 2020 Chemistry (miscellaneous) 2020 Q1 Catalysis 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sánchez-Sánchez, C.
