The compounds were characterized by spectroscopic methods. X-ray crystal structure determination and DFT calculations confirmed their geometry in solution and in the solid phase. Moreover, intermolecular interactions in the crystal structure of K2 were analyzed using 3D Hirshfeld surfaces and the related 2D fingerprint plots. The magnetic study revealed very strong antiferromagnetic CuII-CuII exchange interactions, which were supported by magneto-structural correlation and DFT calculations conducted within a broken symmetry (BS) framework. Complexes K1 and K2 exhibited luminescent properties that may be of great importance in the search for new OLEDs. Both K1 and K2 complexes showed emissions in the range of 392\u2013424 nm in solutions at various polarities. Thin materials of the studied compounds were deposited on Si(111) by the spin-coating method or by thermal vapor deposition and studied by scanning electron microscopy (SEM\/EDS), atomic force microscopy (AFM), and fluorescence spectroscopy. The thermally deposited K1 and K2 materials showed high fluorescence intensity in the range of 318\u2013531 nm for K1\/Si and 326\u2013472 nm for the K2\/Si material, indicating that they could be used in optical devices.<\/jats:p>","DOI":"10.3390\/ijms24033017","type":"journal-article","created":{"date-parts":[[2023,2,6]],"date-time":"2023-02-06T02:57:32Z","timestamp":1675652252000},"page":"3017","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["New Dinuclear Macrocyclic Copper(II) Complexes as Potentially Fluorescent and Magnetic Materials"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6616-337X","authenticated-orcid":false,"given":"Magdalena","family":"Barwiolek","sequence":"first","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Torun, Gagarina 11, 87-100 Torun, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominika","family":"Jankowska","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Torun, Gagarina 11, 87-100 Torun, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4931-8701","authenticated-orcid":false,"given":"Anna","family":"Kaczmarek-K\u0119dziera","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Torun, Gagarina 11, 87-100 Torun, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iwona","family":"Lakomska","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Torun, Gagarina 11, 87-100 Torun, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1745-3562","authenticated-orcid":false,"given":"Jedrzej","family":"Kobylarczyk","sequence":"additional","affiliation":[{"name":"Institute of Nuclear Physics PAN, Radzikowskiego 152, 31-342 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7457-6799","authenticated-orcid":false,"given":"Robert","family":"Podgajny","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University, Gronostajowa 2, 30-387 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1868-3690","authenticated-orcid":false,"given":"Pawe\u0142","family":"Popielarski","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Kazimierz Wielki University, Powstancow Wielkopolskich 2, 85-090 Bydgoszcz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Masternak","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Jan Kochanowski University of Kielce, Uniwersytecka 7, 25-406 Kielce, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9347-2538","authenticated-orcid":false,"given":"Maciej","family":"Witwicki","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, University of Wroc\u0142aw, Joliot Curie 14, 50-383 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5220-4430","authenticated-orcid":false,"given":"Tadeusz M.","family":"Muzio\u0142","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Torun, Gagarina 11, 87-100 Torun, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1016\/j.ccr.2019.03.010","article-title":"Recent developments in penta-, hexa- and heptadentate Schiff base ligands and their metal complexes","volume":"389","author":"Liu","year":"2019","journal-title":"Coord.
