Photoluminescence quantum yields (PLQYs) and single crystal X-ray structures of 100 reported compounds were assembled, %Vbur of the ligand systems were calculated and analyzed for correlations. We found that increased shielding of the central Cu(I) cation relying on shared contributions of both (NN) and (PP) ligand systems led to increased PLQYs. These findings are of relevance for future characterizations of Cu(I)-based complexes and their photophysical behavior in the solid-state.<\/jats:p>","DOI":"10.3390\/molecules25112647","type":"journal-article","created":{"date-parts":[[2020,6,9]],"date-time":"2020-06-09T08:49:11Z","timestamp":1591692551000},"page":"2647","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["The Role of Percent Volume Buried in the Characterization of Copper(I) Complexes for Lighting Purposes"],"prefix":"10.3390","volume":"25","author":[{"given":"Murat","family":"Alkan-Zambada","sequence":"first","affiliation":[{"name":"Laboratory of Inorganic Synthesis and Catalysis, Institute of Chemical Sciences and Engineering, \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), ISIC-LSCI, BCH 3305, 1015 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4916-4041","authenticated-orcid":false,"given":"Edwin C.","family":"Constable","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Basel, BPR 1096, Mattenstrasse 24a, CH-4058 Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8074-0089","authenticated-orcid":false,"given":"Catherine E.","family":"Housecroft","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Basel, BPR 1096, Mattenstrasse 24a, CH-4058 Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2812","DOI":"10.1002\/cber.19671000907","article-title":"Klassifizierung phosphorhaltiger Liganden in Metallcarbonyl-Derivaten nach der \u03c0-Acceptorst\u00e4rke","volume":"100","author":"Strohmeier","year":"1967","journal-title":"Chemische Berichte"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"313","DOI":"10.1021\/cr60307a002","article-title":"Steric effects of phosphorus ligands in organometallic chemistry and homogeneous catalysis","volume":"77","author":"Tolman","year":"1977","journal-title":"Chem.
