A Design of Experiments (DoE) approach, and in particular a Simple Lattice three-components design, was employed for determining the variation of the BGE upon the composition of each system. UV-VIS analysis and subsequent Tauc plot methodology provided the data requested from the DoE, and multivariate statistical analysis revealed a drop of the BGE in correspondence to specific binary compositions for systems A and B. In particular, a BGE of 3.85 eV was registered for the mixtures ChCl\/EtOH (1:1) and ChCl\/2-propanol (1:1), which represents one of the lowest values ever observed for these systems.<\/jats:p>","DOI":"10.3390\/ma14123418","type":"journal-article","created":{"date-parts":[[2021,6,20]],"date-time":"2021-06-20T22:00:02Z","timestamp":1624226402000},"page":"3418","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Behavior of Ternary Mixtures of Hydrogen Bond Acceptors and Donors in Terms of Band Gap Energies"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7623-7475","authenticated-orcid":false,"given":"Alberto","family":"Mannu","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of Turin, Via Pietro Giuria 7, I-10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3237-5408","authenticated-orcid":false,"given":"Francesca","family":"Cardano","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Turin, Via Pietro Giuria 7, I-10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0327-0175","authenticated-orcid":false,"given":"Salvatore","family":"Baldino","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Turin, Via Pietro Giuria 7, I-10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7567-4646","authenticated-orcid":false,"given":"Andrea","family":"Fin","sequence":"additional","affiliation":[{"name":"Department of Drug Science and Technology, University of Turin, Via Pietro Giuria 9, I-10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Mannu, A., Blangetti, M., Baldino, S., and Prandi, C.
