Реферат: A dual-emissive ytterbium complex with a pyrene-substituted Schiff base ligand was synthesized and characterized. The complex exhibits both visible and near-infrared (NIR) emissions, with the emission bands ratio showing a significant temperature dependence in the range of 77–420 K. This feature makes the complex suitable for luminescent thermometry applications including inside of the organic light-emitting diode (OLEDs) emission layer (EML). Several heterostructures with different hole transport layers and different thicknesses of the EML were tested. The OLED1 with thinner EML demonstrate external current efficiency (ECE) up to 30 μW/W while electroluminescence spectra contain both vis and NIR emission bands that make it possible to measure EML temperature which reach up to 77–114 ◦C.
