This interest is attributable to their reversible fluorescence switching behavior, driven by aggregated structural changes associated with phase transitions upon heating and cooling. The research group has developed various PLLCs by incorporating fluorescent \u03c0\u2010conjugated mesogens into donor\u2013\u03c0\u2013acceptor (D\n                    <jats:italic>\u2013<\/jats:italic>\n                    \u03c0\u2013A)\u2010type fluorinated tolanes, functionalized with a range of electron\u2010donating and electron\u2010withdrawing groups (EWGs) at the molecular terminal positions. This article introduces a novel class of D\n                    <jats:italic>\u2013<\/jats:italic>\n                    \u03c0\u2013A\u2010type fluorinated tolanes featuring an imidazole ring, which functions as an EWG with both steric and electronic effects. These compounds exhibit distinct phase transition behaviors and photophysical properties depending on the chain length of the flexible alkoxy units. Furthermore, for compounds exhibiting any LC phase, the PL behavior in the mesophase is evaluated. The results reveal that phase transitions lead to changes in both the fluorescence wavelength and intensity. These findings demonstrate that nitrogen\u2010containing heterocycles, such as imidazole, are effective EWG units with both steric and electronic contributions. As such, they hold promise for the design of PLLCs for use in PL sensing materials.\n                  <\/jats:p>","DOI":"10.1002\/cplu.202500438","type":"journal-article","created":{"date-parts":[[2025,10,3]],"date-time":"2025-10-03T16:50:35Z","timestamp":1759510235000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Chain\u2010Length\u2010Dependent Phase Behavior and Photoluminescence in Imidazole\u2010Substituted Fluorinated Tolane Liquid Crystals"],"prefix":"10.1002","volume":"90","author":[{"given":"Yuto","family":"Eguchi","sequence":"first","affiliation":[{"name":"Faculty of Molecular Chemistry and Engineering Kyoto Institute of Technology  Matsugasaki, Sakyo\u2010ku, Kyoto 606\u20138585 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tadahiro","family":"Hirami","sequence":"additional","affiliation":[{"name":"Faculty of Molecular Chemistry and Engineering Kyoto Institute of Technology  Matsugasaki, Sakyo\u2010ku, Kyoto 606\u20138585 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masato","family":"Morita","sequence":"additional","affiliation":[{"name":"Department of Quantum Beam Science Graduate School of Science and Engineering Ibaraki University  4\u201012\u22121 Nakanarusawa Hitachi, Ibaraki 316\u20138511 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9324-3463","authenticated-orcid":false,"given":"Motohiro","family":"Yasui","sequence":"additional","affiliation":[{"name":"Faculty of Molecular Chemistry and Engineering Kyoto Institute of Technology  Matsugasaki, Sakyo\u2010ku, Kyoto 606\u20138585 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsutomu","family":"Konno","sequence":"additional","affiliation":[{"name":"Faculty of Molecular Chemistry and Engineering Kyoto Institute of Technology  Matsugasaki, Sakyo\u2010ku, Kyoto 606\u20138585 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6379-0447","authenticated-orcid":false,"given":"Shigeyuki","family":"Yamada","sequence":"additional","affiliation":[{"name":"Faculty of Molecular Chemistry and Engineering Kyoto Institute of Technology  Matsugasaki, Sakyo\u2010ku, Kyoto 606\u20138585 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,10,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.molliq.2023.122607"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/agt2.660"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/agt2.70000"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/agt2.613"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/agt2.642"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1039\/D1QM00023C"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dyepig.2021.109272"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.molliq.2024.126060"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dyepig.2025.113035"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/j100153a008"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cplett.2004.02.029"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1021\/jp307896c"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jphotochem.2016.03.023"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0NJ01268H"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1039\/D2ME00057A"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.3390\/molecules28062764"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfluchem.2022.110032"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1039\/C2SC21666C"},{"key":"e_1_2_7_20_1","volume-title":"Gaussian16, Revision B.01","author":"Frisch M.
