The formation of biexcitons in conjugated polymers is examined within the Pariser–Parr–Pople (PPP) model of polyacetylene. The calculations are done using a scattering formalism that provides a size-consistent description of excited states containing both single and double electron–hole pair excitations. The excited-state absorption spectrum from the 1 1Bu exciton state was calculated and examined for signatures of biexciton formation. Calculations were performed on polyenes with up to 9 unit… CONTINUE READING
