Sci. 2019, 10, 10143-10148 DOI:10.1039/C9SC03404H.2041-652010.1039/c9sc03404hhttps://hdl.handle.net/20.500.14352/92567The synthesis of porous nanographenes is a challenging task for solution chemistry, and thus, on-surface synthesis provides an alternative approach. Here, we report the synthesis of a triporous nanographene with 102 sp2 carbon atoms by combining solution and surface chemistry. The carbon skeleton was obtained by Pd-catalyzed cyclotrimerization of arynes in solution, while planarization of the molecule was achieved through two hierarchically organized on-surface cyclodehydrogenation reactions, intra- and inter-blade. Remarkably, the three non-planar 14]annulene pores of this nanographene further evolved at higher temperatures showing interesting intra-porous on-surface reactivity.engjournal article2041-6539https://doi.org/10.1039/c9sc03404hopen access547Ciencias23 Química
