On page 2964 Gabriella Cipparrone and co-workers report on the supramolecular chiral structuring of an amorphous azo-polymer guided by 2D polarization light patterns. Periodic chiral microstructures with spiral- or ribbon-like shape and identical or opposite helicity are demonstrated. They exhibit high stability and complete reconfigurability. These results provide an alternative approach to design a new class of materials with periodic chiral arrangements that have potential advantages for applications in smart functional devices.
