| Summary: | 碩士 === 國立成功大學 === 化學系碩博士班 === 97 === Recently, we develops a new method to synthesize Benzo[k]fluoranthene based linear acenes. Our synthetic design is different from traditional methods that all use Diels-Alder reaction.
In the presence of palladium catalyst and the optimized conditions, total 16 benzo[k]fluoranthene derivatives have been synthesized. The putative synthetic mechanism has been proposed.
Our synthetic design is easy to add both electron donating groups and electron withdrawing groups, included ester, methoxy, butyl or extended more benzene ring, and we utilize o-diiodoarenes to confirm that reaction position and offer a good yield.
We measured representative compounds by UV�{visible, photoluminesc-
ence spectra and hope it can be a find material for OLED.
