10,10'-Dimethoxy-9,9'-biazuleno[2,1-c]phenanthrene

Abstract

The title compound was prepared by the regioselective homocoupling of 10-methoxyazuleno[2,1-c]phenanthrene in the presence of ammonium persulfate. The structure of the synthesized compound was assigned on the basis of its 1H-NMR, FT-IR, and mass spectral data. Its crystal structure and electrochemical properties are also reported.
