Abstract [eng] |
Electroactive organic compounds are used in optoelectronic devices such as organic light emitting diodes, solar cells. Quinazoline fragment was chosen as an acceptor moiety for the synthesis of new electroactive compounds due to its conjugated structure resulting in efficient photophysical properties. Widely used aromatic moieties, such as ditertbutylcarbazole, diterbutyldimethyldihydroacridine and ditertbutylphenohiazine, were used as electron-donating substituents. The materials were synthesized by employing two-step synthesis. In the first step, an acceptor ragment of quinazoline was synthesized by the Friedlander reaction. In the second step, donor fragments were attached to the acceptor quinazoline fragment during nucleophilic substitution or Buchwald-Hartwig reactions. The structures of the compounds were proven by nuclear magnetic esonance spectroscopy and mass spectroscopy. ėjimas https://darbai.labt.lt/redmine/issues/7239. |
