Abstract
Lanthanide complexes Ln(L)(HL) (H 2 L = 2-tosylamino-benzylidene-(2-benzo[d]thiazole) hydrazone; Ln = Yb, Gd) were obtained and thoroughly characterized. The monomeric structure of Yb(L)(HL)·Solv 1 (Solv 1 = 2CH 3 CN + 2EtOH + H 2 O) and the ligand structure were determined by single crystal X-ray diffraction data. Relatively high solubility (ca. 5 g/l) and quantum yield (0,9%), as well as mobility of electrons (2,33·10 −6 cm 2 /V·s) and holes (4,94·10 −7 cm 2 /V·s) of Yb(L)(HL) allowed its successful use as a host-free near-infrared OLED emission layer. OLED with the heterostructure ITO/PEDOT:PSS/poly-TPD/Yb(L)(HL)/OXD-7/LiF/Al demonstrated pure 1000 nm centred near-infrared luminescence with the external quantum efficiency up to 0.025%, which is one of the highest value for 1000 nm centred electroluminescence. • Ytterbium coordination compound Yb(L)(HL)·Solv with 2-tosylamino-benzylidene-(2-benzo[d]thiazole) hydrazone was obtained. • Crystal structures of the complex and the new ligand were determined. • Yb(L)(HL)·Solv demonstrate ytterbium luminescence with the quantum yield up to 0,9% and high solubility. • Mobility of charge carriers was measured (2,33·10 −6 cm 2 /V·s and 4,94·10 −7 cm 2 /V·s for electrons and holes). • Yb(L)(HL)·-based solution-processed host-free OLED demonstrated the pure 1000 nm centred NIR emission at low voltages.
