Getting (Nano)Tubular With Porphyrins
Nanotubes can exhibit exotic electronic properties when their atoms are willing to share delocalized electrons, but growing pristine tubes with prescribed orbital overlaps is a challenge. Researchers led by Harry L. Anderson of the University of Oxford now report a technique that uses porphyrin molecules to form well-defined, π-conjugated nanotubes (Angew. Chem. Int. Ed. 2015, DOI: 10.1002/anie.201502735). The Oxford team first formed porphyrin dimers, . . .
