Simple heating of a dime/dienophile precursor can provide either gram‐quantities of the [6] beltene derivative 1 or a ribbon‐like polymer. Compound 1 is stereochemically uniform, and in the crystalline state it takes the form of flattened, double‐stranded rings. The morphology of the ribbon polymer (with a polymerization degree of 24–330!) resembles a “two‐dimensional coil.” R (CH 2 ) 6 .
