Electro-optic properties of organic nanotubes

► A correct theoretical consideration of the electro-optic (EO) effect of nanotubes has been made. ► A simple equation for the identification of permanent dipole moment has been derived. ► Recommendations for the rapid electro-optic (EO) characterization of organic nanotubes (ONT) have been proposed. ► The agreement between theory and experimental results for organic nanotubes (ONT) has been found to be satisfactory.
