Herein， we present a template approach that allows for the incorporation of normally labile metal centers， such as copper(I)， copper(II)， and silver(I)， into DNA branch points(Scheme 1 a). Remarkably high structural stability and chir-ality transfer to the metal complex are demonstrated. More-over， we have used this approach to generate the first example of a dynamic multimetallic metal–DNA assembly， with three metal complexes as the corners， single-stranded DNA as the sides， and multiple DNA double strands at the periphery (Scheme 1 d). We demonstrate quantitative and reversible structural switching of these metal–DNA nanostructures by adding specific DNA strands， resulting in controlled modu-lation of the metal–metal distances.This contribution thus allows the programmable generation of structurally dynamic multimetallic metal–DNA assemblies， with anticipated appli-cations in nanoelectronics， nanooptics， artificial photosyn-thesis， high-density data storage， and catalysis. To create stable and electroactive metal–DNA junctions，we examined the attachment of the ligand bis(2，9-diphenyl)-1，10-phenanthroline (dpp) to DNA (Scheme 1 a). This ligand has been used by the groups of Sauvage and others to generate interwoven structures.[10]It forms complexes such as [Cu(dpp)2]+， whose redox potential falls within the compat-ible window for DNA bases (+ 0.8 to-0.7V vs. saturated calomel electrode， SCE)
