By monitoring the formation of ZnSe in reactions with and without InP seeds by quantitative absorbance and nuclear magnetic resonance (NMR) spectroscopy, we observe that the ZnSe formation rate is independent of the presence of InP cores. Similar to the seeded growth of CdSe and CdS, this observation supports a ZnSe growth mechanism through the inclusion of reactive ZnSe monomers that form homogeneously in the solution. Furthermore, by combining NMR and mass spectrometry, we identified the dominant reaction products of the ZnSe formation reaction as oleylammonium chloride and amino-substitutions of TOP, i.e., iminophosphoranes (TOP=NR), aminophosphonium chloride salts [TOP(NHR)Cl], and bis(amino)phosphoranes [TOP(NHR)2]. Based on the acquired results, we outline a reaction scheme that involves the complexation of TOP=Se by ZnCl2, followed by the nucleophilic addition of oleylamine onto the Lewis acid activated P\u2013Se bond, thereby eliminating ZnSe monomers and forming amino-substitutions of TOP. Our work highlights the central role of oleylamine, acting as both the nucleophile and Br\u00f8nsted base, in the transformation of metal halides and alkylphosphine chalcogenides into metal chalcogenides.<\/jats:p>","DOI":"10.1063\/5.0144683","type":"journal-article","created":{"date-parts":[[2023,6,8]],"date-time":"2023-06-08T15:43:35Z","timestamp":1686239015000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":4,"title":["Mechanistic study of ZnSe nanocrystal formation from zinc halides"],"prefix":"10.1063","volume":"158","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-9204-9117","authenticated-orcid":false,"given":"Leila","family":"Mingabudinova","sequence":"first","affiliation":[{"name":"Physics and Chemistry of Nanostructures, Department of Chemistry, Ghent University , B-9000 Gent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2106-0283","authenticated-orcid":false,"given":"Luca","family":"Giordano","sequence":"additional","affiliation":[{"name":"Physics and Chemistry of Nanostructures, Department of Chemistry, Ghent University , B-9000 Gent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0950-091X","authenticated-orcid":false,"given":"Mickael D.","family":"Tessier","sequence":"additional","affiliation":[{"name":"Physics and Chemistry of Nanostructures, Department of Chemistry, Ghent University , B-9000 Gent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7041-3375","authenticated-orcid":false,"given":"Zeger","family":"Hens","sequence":"additional","affiliation":[{"name":"Physics and Chemistry of Nanostructures, Department of Chemistry, Ghent University , B-9000 Gent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0178-413X","authenticated-orcid":false,"given":"Pieter","family":"Schiettecatte","sequence":"additional","affiliation":[{"name":"Physics and Chemistry of Nanostructures, Department of Chemistry, Ghent University , B-9000 Gent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2023,6,8]]},"reference":[{"key":"2023111314231916100_c1","doi-asserted-by":"publisher","first-page":"712","DOI":"10.1557\/mrs.2013.184","article-title":"Bright and stable quantum dots and their applications in full-color displays","volume":"38","year":"2013","journal-title":"MRS Bull."},{"key":"2023111314231916100_c2","doi-asserted-by":"publisher","first-page":"1012","DOI":"10.1021\/nn506223h","article-title":"Prospects of nanoscience with nanocrystals","volume":"9","year":"2015","journal-title":"ACS Nano"},{"key":"2023111314231916100_c3","doi-asserted-by":"publisher","first-page":"8706","DOI":"10.1021\/ja00072a025","article-title":"Synthesis and characterization of nearly monodisperse CdE (E = sulfur, selenium, tellurium) semiconductor nanocrystallites","volume":"115","year":"1993","journal-title":"J.
