On-surface synthesis made the fabrication of extended,atomically precise pi-conjugated nanostructures on solid supports possible,with graphene nanoribbons (GNRs) and porphyrin-derived oligomersstanding out. To date, examples combining these two prominent materialclasses are scarce, even though the chemically versatile porphyrins and theatomistic details of the nanographene spacers promise an easy tunability ofstructural and functional properties of the resulting hybrid structures. Here,we report the on-surface synthesis of extended benzenoid- and non-benzenoid-coupled porphyrin-graphene nanoribbon hybrids by sequentialUllmann-type and cyclodehydrogenation reactions of a tailored Zn(II) 5,15-bis(5-bromo-1-naphthyl)porphyrin (Por(BrNaph)2) precursor on Au(111)and Ag(111). Using bond-resolved noncontact atomic force microscopy (nc-AFM) and scanning tunneling microscopy (STM), we characterize thestructures of reaction intermediates and products in detail and provide insight into the effects of the annealing protocol. We furtherdemonstrate the stability and rigidity of the extended one-dimensional porphyrin-GNR oligomers by employing an STM-basedmanipulation procedure, which allows for spectroscopic measurement upon lifting.
