Synthesis and photophysical studies of novel 4-aryl substituted 2-phenyl-, 2-(fluoren-2-yl)- and 2-cymantrenylquinazolines

The synthesis of novel push–pull 2,4-disubstituted quinazolines was performed by the bromodeoxygenation of 2-phenyl-, 2-(fluoren-2-yl)- and 2-cymantrenylquinazolin-4-ones and subsequent palladium-catalyzed Suzuki reactions. According to the optical studies, derivatives containing 4-positioned 4-diethylaminophenyl substituent exhibit higher luminescence in toluene solutions as compared to acetonitrile ones.
