An approach to the construction of the molecular switch based on electrical properties of a conjugated polymer chain containing chemically attached photochromic side groups is presented. Upon changing the structure of the photochromic units by light, the ionization energy of the polymer segments containing the dipolar species and energies of electrostatic interactions of charge carriers on the molecular wire and the dipoles are locally modified and a potential-well structure is formed.
