Expanded porphyrins have been received great interest due to the extended π-conjugation,multi-metal coordination,and multiple oxidation states,which consequently make them to be useful for optoelectronic applications,especially in the near-infrared (NIR) region.In contrast to the standard porphyrin with rigid planarity,expanded porphyrins are generally rather flexible and show the uncommon electronic and/or electromagnetic behavior.However,the large flexibility of the molecules allows them to take various structures with many conformers and tautomers,which sometimes makes the metal coordination difficult and unpredictable.Thus,it has been awaited to advent the rigid-shaped expanded porphyrins possessing a large cavity that can accept bis-metals in the core without difficulty.
