1. To investigate spectral properties of the synthesized compounds

Tasks of the working activity:

1.     To perform analysis of academic literature and patents.

2.     To measure spectrum of absorption and fluorescence in various environments or in a solid state

3.     To compare spectral characterizations of the researched substances, to select the most perspective fluorophores. 

In the beginning of commencement of the activity and also in later stages, the latest academic works and patents will be analyzed.

It is planned to investigate fluorescence peculiarities of compounds obtained in activity No.2 in different solvents (in different concentrations), in polymer matrixes and in a condensated condition. With spectrophotometrical and spectrofluorometrical methods the corresponding spectra will be taken, wherefrom such important properties of fluorescent dyes as molar extinction coefficients, fluorescence quantum yields, Stokes shifts will be calculated.

Then it is planned to compare the obtained data with properties of fluorescent probes described in literature and used in commerce in order to make a more perspective selection of pigments for fluorescent material and method development within the activities No. 4–7. We will use the obtained data also in activity No. 8 for comparison of optical property modeling results, as well as for development of a database. 

Laboratory premises of Department of Chemistry, G. Liberts Innovative Microscopy Centre of Daugavpils University and the following academic equipment will be used in work (spectrophotometer “CECIL 1021”, spectrofluorometer “FluoroMax-3”, microscopes – confocal laser-scanning microscope Leica TSCP-5, epi-fluorescent microscope Zeiss Axioskop 40.
