A Facile Synthesis for One Novel N-Heteroacene 9, 11, 20, 22-Tetraaza-Tetrapyridopentacene and Its Mechanism Analysis

ABSTRACT

N-heteroacenes have received significant attention due to their unique properties, especially in applications of organic electronics. 9, 11, 20, 22-tetraaza-tetrapyridopentacene (TTP) has been prepared under two conditions, respectively. It is found that with addition of 2-iodoxybenzoic acid (IBX) as a catalyst, the yield of TTP rises from 83% to 94%, and the mechanism for this phenomenon is analyzed. After purified by physical transport sublimation, TTP was characterized by MALDI-TOF, FT-IR, and TGA. The structure of TTP has been solved by single-crystal X-ray diffraction analysis as well. All the results indicate TTP exhibits promising potential for applications in organic semiconductor devices.
