Vernier templating and synthesis of a 12-porphyrin nano-ring

Anderson and coworkers used a circular hexapyridyl template with six binding sites. They combined the template with four-membered zinc porphyrin chains, with the porphyrins linked by butadiyne groups. Three porphyrin tetramers can bind around and occupy all of the binding sites on two of the templates, linking the two in the process. The researchers then oxidatively coupled the template-bound porphyrin tetramers to form a figure-eight compound. Dissociating the porphyrins from the templates produced a 12-membered, π-conjugated porphyrin nanoring, among the largest of similar macrocycles ever synthesized.

The method is based on Vernier complexes, which are precise assemblies generated by the coming together of components with different numbers of binding sites—for example, different four- and six-membered building blocks. Past experiments with Vernier systems, however, have all involved linear complexes. In the new work, a group led by , a chemistry professor at , experimented with radial templates and linear building blocks to produce 12-membered porphyrin nanorings.

Vernier Templating and Synthesis of a 12-Porphyrin Nano-Ring.

We illustrate the value of this concept forthe covalent synthesis of challenging targets by using a simple six-sitetemplate to direct the synthesis of a 12-porphyrin nano-ring with adiameter of 4.7 nm, thus establishing Vernier templating as apowerful new strategy for the synthesis of large monodispersemacromolecules.
