Two dinuclear copper(II) complexes with macrocyclic Schiff bases <b>K1</b> and <b>K2</b> were prepared by the template reaction of (<i>R</i>)-(+)-1,1′-binaphthalene-2,2′-diamine and 2-hydroxy-5-methyl-1,3-benzenedicarboxaldehyde <b>K1</b>, or 4-<i>tert</i>-butyl-2,6-diformylphenol <b>K2</b> with copper(II) chloride dihydrate. 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 <b>K2</b> were analyzed using 3D Hirshfeld surfaces and the related 2D fingerprint plots. The magnetic study revealed very strong antiferromagnetic Cu^II-Cu^II exchange interactions, which were supported by magneto-structural correlation and DFT calculations conducted within a broken symmetry (BS) framework. Complexes <b>K1</b> and <b>K2</b> exhibited luminescent properties that may be of great importance in the search for new OLEDs. Both <b>K1</b> and <b>K2</b> complexes showed emissions in the range of 392–424 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 <b>K1</b> and <b>K2</b> materials showed high fluorescence intensity in the range of 318–531 nm for <b>K1</b>/Si and 326–472 nm for the <b>K2</b>/Si material, indicating that they could be used in optical devices.
