Single-Acetylene Linked Porphyrin Nanorings

[Image: see text] The synthesis of ethyne-linked porphyrin nanorings has been achieved by template-directed Sonogashira coupling. The cyclic hexamer and octamer are predicted by density functional theory to adopt low symmetry conformations, due to dihedral twists between neighboring porphyrin units,...

description [Image: see text] The synthesis of ethyne-linked porphyrin nanorings has been achieved by template-directed Sonogashira coupling. The cyclic hexamer and octamer are predicted by density functional theory to adopt low symmetry conformations, due to dihedral twists between neighboring porphyrin units, but their symmetries are effectively D(6h) and D(8h), respectively, in solution by (1)H NMR. The fluorescence spectra indicate that the singlet excited states of these nanorings are highly delocalized.
