Original Abstract
Proposed switch consist of molecular wire ( - and conjugated polymers) which side chains contain reversible photochromic moieties. The chemical structure of the side chains strongly affects electron structure of the polymer, the energy of the gap and optical properties above all. Very often the dipole moment of the metastable form of photochromic system is higher than that of the stable form, and this feature allows control of the polymer chain conjugation, and hence a change in the on-chain mobility of charge carriers. Thus, a molecular switch is based on the principle of controlled electrical conductivity of the polymer. - and conjugated polymers, polymers with photochromic side chains or with side chains containing functional groups able to change their dipole moment by light seems to be a favourable materials for molecular switch
