Nonacene generated by on-surface dehydrogenation
The on-surface synthesis of nonacene has been accomplished by dehydrogenation of an air-stable partially saturated precursor, which could be aromatized by using a combined scanning tunnelling and atomic force microscope (STM/AFM) tip as well as by on-surface annealing. This transformation allowed th...

| Sumario: | The on-surface synthesis of nonacene has been accomplished by dehydrogenation of an air-stable partially saturated precursor, which could be aromatized by using a combined scanning tunnelling and atomic force microscope (STM/AFM) tip as well as by on-surface annealing. This transformation allowed the in-detail analysis of the electronic properties of nonacene molecules physisorbed on Au(111) by scanning tunnelling spectroscopy (STS) measurements, which were corroborated by density theory functional (DFT) calculations thus confirming the spatial mapping of its molecular orbitals. Furthermore, the thermally-induced dehydrogenation uncovered the isomerisation of intermediate dihydrononacene species, which allowed for their in-depth structural and electronic characterization. |
