Surface ligand engineering plays a crucial role in regulating the electroluminescent performance and device stability of perovskite NCs. Here, we develop a cooperative 2-(4-(methylsulfonyl)phenyl)ethylamine (MSPE)-hydrogen halide (HX, X = Br, I) ligand-exchange strategy that enables surface reconfiguration and robust passivation of perovskite NCs. In this approach, HX assists in removing insulating long-chain ligands (oleic acid and oleylamine), thereby exposing additional undercoordinated surface sites and promoting firm double-end anchoring of in situ protonated MSPE through bidentate interactions. Spectroscopic and electrical analyses reveal that the strengthened ligand\u2013nanocrystal interface effectively suppresses trap-assisted nonradiative recombination, increases the exciton binding energy from 97.7 to 168.9 meV, prolongs the lifetime from 9.5 to 12.3 ns, and reduces trap densities in CsPbBr3 NC films. As a result, the photoluminescence quantum yield of CsPbBr3 NCs after MSPE-HBr treatment is enhanced to 96.1%, and LEDs fabricated with MSPE-HBr-treated NCs deliver a peak external quantum efficiency of 25.2% and display excellent device-to-device reproducibility. This cooperative ligand-exchange strategy provides an effective pathway for achieving high surface coverage of robust multidentate ligands, offering a promising route toward highly efficient and stable perovskite LEDs.<\/jats:p>","DOI":"10.1021\/acsami.6c14902","type":"journal-article","created":{"date-parts":[[2026,10,15]],"date-time":"2026-10-15T08:01:32Z","timestamp":1792051292000},"source":"Crossref","is-referenced-by-count":0,"title":["Etching-Assisted Double-End Anchoring of Ligands for High-Performance CsPbBr3 Light-Emitting Diodes"],"prefix":"10.1021","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-0192-8455","authenticated-orcid":true,"given":"Guiyuan","family":"Liu","sequence":"first","affiliation":[{"name":"Huazhong University of Science and Technology , , ,","place":["Wuhan, P.
