The crystal structure of the title compound, C31H16BN7O, (CNPhO-BsubPc) is characterized by pairs of π–π stacking interactions between the concave faces of inversion-related BsubPc fragments with a centroid–centroid distance of 3.600 (1) . In addition, these pairs of molecules are linked into chains along [101] through further weak π–π stacking interactions with a centroid–centroid distance of 3.8587 (9) . There are also weak C—H...π(arene) interactions within the chains.
