Abstract

   Subphthalocyanine (SubPc) is a phthalocyanine analog with the lowest molecular weight, having a molecular structure with one isoindole moiety less than that of phthalocyanine. Subphthalocyanine is an aromatic compound having a 14π-conjugated system, and because of its unique nonlinear optical characteristics and strong fluorescence, it is expected to have applications in various fields. Further, the molecule has a non-planar structure, so that it has an advantage of excellent solubility as compared to phthalocyanine. In this research, we attempted to synthesize subphthalocyanines having pyrazine rings (SubPc), as well as fluorine-substituted pyrazine rings (SubPcF). In this SubPcF, with the introduction of the electron-withdrawing substituent to the phenyl group, the color tone was also red and a large difference in the pectroscopic analysis could not be confirmed.
