With the aim of designing new heteroorganic ligands capable of sensitizing the metal-centered photoluminescence (PL) of YbIII through the redox mechanism, a new diselenide, 2,2′-(diseleno-2,1-diphenylene)bis[benzothiazole] ((SeSN)2, 1), was synthesized and structurally characterized. The selenophenolate complexes Na(SeSN)(DME)2(2) and Yb(SeSN)3·0.5 THF (3) were synthesized by the reactions of diselenide 1 with Na and Yb metals in liquid ammonia. Complex 2 showed intense PL at 77 K in a DME solution, which appears as a broad band with a maximum at 575 nm assigned to the phosphorescence of the organoselenide ligand. In the crystalline state, ytterbium complex 3, which was isolated and structurally characterized as an adduct with THF, exhibited intense metal-centered PL in the 980–1100 nm region. This PL is observed upon direct excitation or upon excitation through SeSN ligands (250–380 nm), as well as through excitation of the ligand-to-metal charge transfer (LMCT) band in the 430–700 nm region. The presence of low-energy LMCT states capable of sensitizing the metal-centered PL of YbIII in complexes with organoselenide ligands is responsible for a significant reduction of the Stokes shift of luminescence and opens up new prospects for the development of lanthanide-containing infrared luminophores exhibiting luminescence under long-wavelength excitation.
