Typically, light emission in such devices results from transitions between molecular states, although in the presence of light-matter coupling, the emission can result from a transition between hybrid light-matter states. Here, we create single metal-molecule-metal junctions and simultaneously collect conductance and electroluminescence data using a scanning tunneling microscope (STM) equipped with a custom spectrometer. Through experimental analysis and electronic structure calculations, we provide evidence for a molecule-electrode interfacial exciton coupled to a junction cavity plasmon. Importantly, we find that close to resonant transport conditions, the molecular junction functions as a single emitter that is strongly coupled to the junction cavity mode, leading to characteristic Rabi splitting of the emission spectrum and providing the first example of an electroluminescence-driven single-molecule system in the regime of strong light-matter coupling."}],"article_type":"original","OA_type":"closed access","author":[{"last_name":"Paoletta","full_name":"Paoletta, Angela L.","first_name":"Angela L."},{"last_name":"Hoffmann","first_name":"Norah M.","full_name":"Hoffmann, Norah M."},{"first_name":"Daniel W.","full_name":"Cheng, Daniel W.","last_name":"Cheng"},{"first_name":"Emma","full_name":"York, Emma","last_name":"York"},{"last_name":"Xu","first_name":"Ding","full_name":"Xu, Ding"},{"last_name":"Zhang","first_name":"Boyuan","full_name":"Zhang, Boyuan"},{"first_name":"Milan","full_name":"Delor, Milan","last_name":"Delor"},{"first_name":"Timothy C.","full_name":"Berkelbach, Timothy C.","last_name":"Berkelbach"},{"orcid":"0000-0002-6957-6089","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","first_name":"Latha","full_name":"Venkataraman, Latha","last_name":"Venkataraman"}],"scopus_import":"1","publisher":"American Chemical Society","pmid":1,"date_updated":"2025-10-23T13:03:41Z","intvolume":"       146","doi":"10.1021/jacs.4c09782","citation":{"apa":"Paoletta, A.
