| Popis: | The approach to the directed synthesis of lanthanide aromatic carboxylates – precursors to the electroluminescent materials, - was proposed, namely the conjugation length increase and heteroatom introduction in the appropriate position in combination with the neutral ligand introduction. This resulted in the isolation of a series of new lanthanide complexes, among which the highest electroluminescence efficiency was obtained for mixed-ligand europium benzothiazole-2-carboxylate with bathophenanthroline in a solution-processed OLED. The peculiarities of energy transfer processes allowed obtaining luminescence thermometer materials based on this system, which demontrated the sensitivity of 2.8%/K in the physiological range. |
