A dinuclear naphthalocyanine analogue containing two incomplete naphthalocyanine macrocycles connected by a shared benzene ring was synthesized in good yield. The long‐wavelength absorption band in the electronic spectrum is observed at λ = 965 nm. As a consequence of the π‐system extension caused by dimerization and addition of further peripheral benzene rings, this band is shifted bathochromically by approximately 300 nm compared to absorption bands of mononuclear phthalocyanines.
