The aim of this project is to deepen the student’s scientific competencies. A series of electroactive compounds with different donor and acceptor fragments will be synthesized during the research. Thermal and morphological transformations of materials will be investigated by differential scanning calorimetry and thermogravimetric analysis. The performed studies will allow to evaluate the resistance of the newly synthesized material layers to large temperature changes over a longer period of time. The electrochemical stability, HOMO and LUMO energy values of the synthesized compounds will be determined by cyclic voltammetry. UV spectroscopy will be used to study the optical properties of new emitters. In order to determine the nature and efficiency of photoluminescence of new materials, the kinetics of photophysical processes (lifetimes of photoluminescence) will be evaluated, and the quantum efficiencies of photoluminescence will be determined.
Project funding:
Project is funded by EU Structural Funds according to the 2014–2020 Operational Programme for the European Union Funds’ Investments priority “Development of scientific competence of researchers, other researchers, students through practical scientific activities” under Measure No. 09.3.3-LMT-K-712.
Project results:
During this research, the student’s practical skills in working in an organic synthesis laboratory will be developed. New methods of synthesis, purification and structural analysis of organic compounds will be introduced. Research will synthesize a series of electroactive compounds for organic light emitting diodes with various donor and acceptor moieties. Structural analysis will be performed by nuclear magnetic resonance, infrared spectroscopy and mass spectrometry. Thermal and morphological transformations of materials (layers) will be investigated by methods of differential scanning calorimetry and thermogravimetric analysis. The performed studies will allow to evaluate the resistance of the newly synthesized material layers to large temperature changes over a longer period of time. The electrochemical stability, HOMO and LUMO energy values ??of the synthesized compounds will be determined by cyclic voltammetry. UV spectroscopy will be used to study the optical properties of new emitters. The nature and characteristics of the emission of compounds will be investigated by evaluating their quantum yields, emission lifetimes, and wavelengths of radiation. A detailed study of the properties of the new compounds will allow the student to delve into and analyze in more detail the dependence of the properties of electroactive materials on their structure.
