Abstract
Due to the rapid development of technology, the need for new types of measurement systems for thermodynamic measurements of state parameters such as pressure and temperature is growing. As part of the research works, several series of europium(III) complexes were tested for the role of luminescent molecular sensors for monitoring the temperature of the system. In the first stage of work, the spectroscopic characteristics of the analyzed luminophores were examined. For this purpose, their absorption and emission spectra were measured in acetonitrile. Then the temperature calibration of these sensors was made, by measuring their emission spectra in hardened polymer matrices at different temperatures ranging from 10°C to 40°C. In the next stage of the work, the photostability and the immunity of the analyzed temperature sensors for disturbances of the system parameters in the form of polarity and microviscosity fluctuations of the medium were tested. The photostability and immunity of the sensors for disturbances of the system were measured by measuring the change in emission characteristics of the sensors during the radical photopolymerization process of the model acrylic monomer - TMPTA, during light irradiation at 320 nm for 750 seconds, at a constant temperature of 25°C. These measurements were made using a specially adapted system for kinetic measurements using Fluorescent Probe Technology. Finally, the possibility of using the proposed new europium(III) complexes for the role of luminescent sensors to monitor the system temperature was determined and their potential practical applications were proposed.
