Abstract

ABSTRACT The carbazole derivatives 5a–h were synthesized by four steps involving Suzuki coupling of boronic acid 1 with 1-bromo-2-nitrobenzene, followed with the Cadogan ring closure reaction. Their UV and photoluminescence properties are also reported, and the compounds showed medium-to-strong photoluminescence between 370 and 446 nm at the concentration of 1× 10− 5 M CH 2 Cl 2. Also, the X-ray structure of the carbazole derivative ...
