A molecular wire is forged into a smooth ring—not by the blacksmith's fire, as shown in the background of the picture—but by the vicelike grip of an octadentate template. H. L. Anderson and co‐workers describe in their Communication on page 3122 ff. how a linear porphyrin oligomer can be cyclized to generate a highly symmetric belt‐shaped π system (image by M. Hoffmann; background photograph by J. McNerney, Yukon Forge, www.yukonforge.com).
