Description:

The three laboratories of the research group (No. 402, 404 and 410) see the syntheses of heterocyclic compounds done, by both classic and non-classic procedures (chemical, photochemical and electrochemical approaches, even those using ultrasound and microwaves), as well by methods of green chemistry, supported by the existing infrastructure: ATR FT IR and UV for ascertaining structure of intermediates, obtained by solid-support syntheses, a microwave reactor C3EM for organic synthesis, equipped with power control, controlled pressure, temperature and time measurement.

The generated special oligomers are small molecules with pronounced opto-electronic properties, which play an important role in building novel attractive materials sans defect polymers and preparation of strictly defined optoelectronic devices at molecular level. Designing molecules with electronic defects, removal of selected substituents or terminal groups, required for blocking or releasing functional groups required devices at molecular level, or possess other specific utility functions such as hydrophilic, hydrophobic, electron-donating and electron-withdrawing.

Synthesis of small molecules, based on activated enolethers, with potential bioactivity; pyrazoles, isoxazoles, pyrimidines, quinolines and quinolones stripped of substituents, substituted or with fused  rings, serving for UV photoactivation or anticancerogenic activity. Preparation of analogs and models of known quinolone type drugs carrying  fluorines, nitro group, selenadiazole skeleton a etc.
