Аннотация: New tetranuclear heteroleptic complexes [Er4(dbm)6(O-btd)4(OH)2] (1) and [Er4(dbm)4(O-btd)6(OH)2] (2) (O-btd = 4-hydroxo-2,1,3-benzothiadiazolate and dbm = dibenzoylmethanide) and their solvates with toluene, THF and CH2Cl2 were prepared using two synthetic approaches. The structures of the products were confirmed by single-crystalПоказать полностьюX-ray diffraction. Magnetic properties of 1 and 2 are in good agreement with X-ray data. The effective magnetic moment (?eff) values at 300 K for 1 and 2 corresponds to a system of 4 non-interacting Er(iii) ions in the ground state 4J15/2 with g = 6/5. At ambient temperature and upon excitation with ?exc = 450 nm, complexes 1 and 2 exhibit luminescence at ?1530 nm, i.e. in the near infra-red (NIR) region. The luminescence intensity grows with increasing the number of the (O-btd)- ligands in the complexes. This observation suggests (O-btd)- as a new efficient antenna ligand for the lanthanide-based NIR luminescence. © The Royal Society of Chemistry 2015.
