In this paper, we report the novel synthesis of thieno[2,3-c]acridine and furo[2,3-c]acridine derivatives via an intramolecular iodocyclization reaction. The thieno[2,3-c]acridine derivatives exhibited blue fluorescence in hexane. DFT and time-dependent (TD) DFT studies were carried out. This methodology provided a novel pathway to access thieno[2,3-c]acridine and furo[2,3-c]acridine derivatives via a 6-endo iodocyclization reaction.
