Nickel porphyrin nanotweezers.
A strapped chiroporphyrin free base with two 8-methylene chains linking two adjacent meso-substituents was synthesized as the alpha 4 conformer; insertion of Ni(II) triggered a complete conversion to the alpha beta alpha beta complex, and demetallation totally regenerated the strapped free base in the alpha 4 conformation.
