Abstract

We show that soliton-like charge storage configurations are formed in β-carotene upon p-doping by intermolecular charge transfer. The charge storage states are characterized by a single-intragap absorption band, by zero spin, and by significant structural (bond length) relaxation. The similarity to the charged solitons observed in trans-polyacetylene demonstrates the important role of solitons in finite conjugated chains.
