Structure analysis revealed that these layered structures were due to charge transfer, \u03c0\u2013\u03c0 interactions and hydrogen bonding. Density functional theory (DFT) calculations show that fluoranthene\u2013TCNB and fluoranthene\u2013TFP have charge-transfer properties, while fluoranthene\u2013OFN does not, indicating that fluoranthene\u2013OFN has arene\u2013perfluoroarene (AP) interactions, which was also demonstrated by spectroscopic analysis, which shows that the photophysical properties of luminescent materials can be tuned by forming cocrystals. These results all prove that utilizing supramolecular cocrystals to develop new fluorescent materials is an effective strategy, which has much potential in optoelectronic applications.<\/jats:p>","DOI":"10.1107\/s2053229621008652","type":"journal-article","created":{"date-parts":[[2021,8,24]],"date-time":"2021-08-24T17:36:56Z","timestamp":1629826616000},"page":"551-560","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":6,"title":["Synthesis of luminescent cocrystals based on fluoranthene and the analysis of weak interactions and photophysical properties"],"prefix":"10.1107","volume":"77","author":[{"given":"Pengfei","family":"Wu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Long","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuwei","family":"Xia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangmin","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2021,8,24]]},"reference":[{"key":"dg3020_bb1","doi-asserted-by":"crossref","first-page":"3320","DOI":"10.1063\/1.1677699","volume":"56","author":"Bader","year":"1972","journal-title":"J.
