Existing approaches, including extreme ultraviolet lithography, block copolymer self\u2010assembly, and colloidal nanocrystal patterning, struggle to reliably achieve such dimensions while maintaining long\u2010range order and structural fidelity. Here, we present a pattern transfer technique from a supramolecular dendrimer templating strategy that enables highly ordered sub\u20103\u00a0nm ruthenium\u2010based nanostructures over large areas (1 \u00b5m\u00a0\u00d7\u00a01 \u00b5m). The pristine dendrimer template forms a hexagonally packed cylindrical morphology with sub\u20105\u00a0nm periodicity, exhibiting structural stability and long\u2010range order. Thermal annealing induces cooperative self\u2010assembly into a single\u2010domain array, which is selectively stained with RuO\n                    <jats:sub>4<\/jats:sub>\n                    to generate an inorganic RuO\n                    <jats:sub>2<\/jats:sub>\n                    core while preserving structural registry. This Ru\u2010incorporated dendrimer architecture shows markedly enhanced thermal and structural stability. Electron microscopy and elemental mapping confirm vertically aligned cylindrical domains with high pattern fidelity. Subsequent calcination at 250\u00b0C removes unstained organic components without structural collapse, yielding periodic Ru\u2010based nanostructures with a characteristic feature size of \u223c2.5\u00a0nm. This work establishes a versatile bottom\u2010up platform for ultrahigh\u2010resolution patterning beyond current lithographic limits and provides a scalable route toward next\u2010generation nanoelectronic, catalytic, and quantum device architectures.\n
