Two-dimensional, π-conjugated coordination nanosheets (CONASHs) have attracted significant attention because of their potential applications in electronics and electrode materials. However, multilayer stacking induced by π–π interlayer interaction originating from flat chemical structures shields the metal complex sites decreases performance. The triptycene-linker ligands CONASHs form square-planar complexes perpendicular to horizontal planes nanosheets, C–H bonds ligand are directed out plane. These features prevent interactions expose axial positions pores. In this study, 2,3,6,7,14,15-hexaaminotriptycene (HATT) was used as a synthesize triptycene-bridged bis(diimino)nickel (Ni-HATT) film using gas–liquid interfacial synthesis method. Facile exfoliation into thin several nanometers thick with lateral dimensions few micrometers achieved ultrasonication isopropanol owing weakened interactions. Furthermore, Ni-HATT-modified electrodes prepared an electrochemical oxidation method exhibited greater hydrogen evolution reaction (HER) electrocatalytic performance than modified conventional CONASH composed flat-conjugated easy access active realized structure design obtained introduction HATT ligand.
