Carbon rods 1‐5 up to five nanometers long are formed by oxidative polymerization of trans ‐bis(triisopropylsilyl)‐protected tetraethynylethene with phenylacetylene as end‐capping reagent. The X‐ray crystal structures of 1 and 2 show perfectly planar, conjugated carbon frames. Compounds 1–5 are readily reduced; the number of reversible one‐electron reductions equals the number of tetraethynylethene moieties in each molecular rod. TIPS = triisopropylsilyl.
