A mixed-condensation reaction of 1,8-dicyanonaphthalene and phthalonitrile provided a novel subphthalocyanine analogue bearing a six-membered ring. This analogue retained the 14pi aromatic characteristics of subphthalocyanine, and spectroscopic and electrochemical properties were largely altered. In this report, sysnthesis, X-ray analysis, absorption and MCD spectra, and electrochemical results will be presented with the assistance of theoretical calculations.
