Axially arylene-bridged “dumbbell” subporphyrin oligomers 3–5 have been synthesized by reactions of B-methoxy subporphyrin with bromoaryl Grignard reagents followed by reductive coupling with Ni(cod)2. Following the same synthetic sequence, subporphyrin tetramer 8 has been synthesized, which shows a nanocage structure consisting of doubly biphenylene-bridged two meso-meso linked subporphyrins and exhibits
