Description:
Front Cover: Azobenzene undergoes E‐Z‐isomerization upon irradiation. Polarized interfering light beams causing repeated isomerization cycles and a photoreorientation of the azobenzene groups result in a massive mass transport over μm distances. Employing polymers with different concentrations of photoactive groups it was investigated how many molecular motors are necessary to get polymer moving. Further details can be found in the Full Paper by V. Börger, O. Kuliskovska, K. G.‐Hubmann, J. Stumpe, M. Huber, and Henning Menzel* on page 1488.
