Abstract The synthesis of a new series of photoluminescent compounds, namely 5, 8-diaryl quinoxaline derivatives (aryl= phenyl, 4-fluorophenyl, 4-methoxyphenyl, and 4- cyanophenyl), was achieved by a direct Suzuki cross-coupling reaction with the employment of a NCP-pincer palladacycle. The electrochemical and photophysical properties of these compounds were also investigated. Four new 4, 8-diaryl-2, 1, 3-benzothiadiazoles were ...
