The photophysical properties were correlated with different solvent parameters, such as the Kamlet\u2013Abraham\u2013Taft (KAT), Catal\u00e1n, and Laurence solvent scales, suggesting that the behavior of BZCH is influenced by both nonspecific and specific solvent-solute interactions. The Catal\u00e1n solvent dipolarity\/polarizability parameters were found to have a significant role in the solvatochromic behavior, which is also confirmed by the KAT and Laurence models. The acidochromism and photochromism properties of this sample in dimethylsulfoxide and chloroform solutions were also investigated. The compound showed reversible acidochromism after the addition of dilute NaOH\/HCl solutions, accompanied by a change in color and the appearance of a new absorption band (514 nm). The photochemical behavior was also examined by irradiating BZCH solutions with both 254 and 365 nm light.<\/jats:p>","DOI":"10.3390\/ijms24065286","type":"journal-article","created":{"date-parts":[[2023,3,10]],"date-time":"2023-03-10T02:30:33Z","timestamp":1678415433000},"page":"5286","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Solvatochromism, Acidochromism and Photochromism of the 2,6-Bis(4-hydroxybenzylidene) Cyclohexanone Derivative"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9432-5479","authenticated-orcid":false,"given":"Mihaela","family":"Homocianu","sequence":"first","affiliation":[{"name":"\u201cPetru Poni\u201d Institute of Macromolecular Chemistry, 41A, Grigore Ghica Voda Alley, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8544-5671","authenticated-orcid":false,"given":"Diana","family":"Serbezeanu","sequence":"additional","affiliation":[{"name":"\u201cPetru Poni\u201d Institute of Macromolecular Chemistry, 41A, Grigore Ghica Voda Alley, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9017-9926","authenticated-orcid":false,"given":"Vlad Bubulac","family":"Tachita","sequence":"additional","affiliation":[{"name":"\u201cPetru Poni\u201d Institute of Macromolecular Chemistry, 41A, Grigore Ghica Voda Alley, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"24","DOI":"10.1080\/15421406.2019.1581708","article-title":"Amphiphiles as novel solvents for photochromics: Stability and photophysical properties","volume":"684","author":"Corici","year":"2019","journal-title":"Mol.
