Abstract The biexciton in conjugated polymers is studied in the Su-Schrieffer-Heeger model appended by a long-range Coulomb interaction. The wave function of the biexciton is constructed in the Heitler-London approach and, for the first time, the binding energy and radius of the biexciton in conjugated polymers is calculated.
