Sublimable Single Ion Magnets Based on Lanthanoid Quinolinate Complexes: The Role of Intermolecular Interactions on Their Thermal Stability

“…A modified approach of the synthesis of lanthanide tetrakis complexes described by Van Deun and others ,, was used to obtain a family of pure tetrakis complexes of general formula, Na­[Ln­(5,7-X 2 q) 4 ], where the ligands are 5,7-dibromo-8-hydroxyquinoline (5,7-Br 2 q) and 5,7-chloroiodo-8-hydroxyquinoline (5,7-ClIq); see sections S.1.1.–S.1.3. in the Supporting Information.…”

“…27,28 A straightforward strategy toward this goal consists in obtaining magnetic molecules that are chemically stable upon sublimation. 10,24−28 In this context, quinoline-based materials stand out as promising compounds for the development of optoelectronic 29,30,34,35,37 and magnetic devices. 31 In particular, the preparation of mononuclear lanthanoid-quinoline compounds of type NaLnq 4 , where q = 8-hydroquinolinate anion, which are the magnetic analogues of the extensively used Alq 3 , 32 have been found to display a rich chemistry.…”

Sublimable chloroquinolinate lanthanoid single-ion magnets deposited on ferromagnetic electrodes

“… 43 , 44 Sublimable ionic molecules based on mononuclear complexes with the 8-hydroxyquinolinato ligand are also known. We also mention the series Li[Ln(q) 4 ] (Ln = La; Y and La; Y and Lu) 46 and the compound Na[Er(q) 4 ], 47 which have been thermally deposited on ITO and gold, and used in the fabrication of OLEDs, thus corroborating the robustness of the quinolato complexes.…”
