Liquid Crystals Laboratory
- Keywords: Multistep synthesis, OLED, Purification
The main job of the laboratory 鈥� working out of new processes, suitable for production and deep purification of target organic compounds.
Research group activities
Organic electronics 鈥� that鈥檚 a recent stage of electronics, based on use of organic compounds, mainly developed as a mean of visualization of information 鈥� that鈥檚 well kown LC screens, OLED screens, development of the last generation lighting devices. The Liquid Crystal Laboratory works in this field 鈥� working out new compounds and their production processes - since 1972. Along with an usual job of scientists 鈥� preparation and examination of new compounds and publication of results, this Laboratory prepares and supplies organic compounds to reagent catalog companies and direct industrial users. Along with relatively simple compounds (such as alkylbenzenes and their functional derivatives) we also synthesize complex high-purity materials - such as liquid crystals (tolans, phenylpyrimidines), intermediates for OLED and other fields. Depending on the structure of the compound, the compounds are in prepared quantities from grams to several kilograms, they are purified to a very high degree of purity - from an usual +98% purity simple compounds to +99.95% purity for some liquid crystals.
Our main research fields:
- Synthesis methods for nitrogen and sulphur heterocycles, highly branched aromatic compounds.
- New compounds and intermediates for OLED technology.
- Efficient technology for ultra-pure liquid crystal and OLED intermediates.
- The synthesis of organic compounds by methods known from the literature.
- A working out new methods of synthesis of selected structure organic compounds.
Proposal
- Working out new processes for production of target compounds;
- Preparation of new compounds for R&D stage.
