Efficient Approach to Electron-Deficient 1,2,7,8-Tetraazaperylene Derivatives

Using an efficient synthetic strategy, a novel class of 1,2-diazine-embedded perylenes, namely 1,2,7,8-tetraazaperylene derivatives, have been successfully synthesized. These molecules were fully characterized by X-ray diffraction analysis, optical spectroscopy, and electrochemistry. The low-lying lowest unoccupied molecular orbital (LUMO) level of these molecules suggests their potential as good electronic acceptors.
