Control and modulation of chirality for azobenzene-substituted polydiacetylene LB films with circularly polarized light.
Herein, photo-controlled rearrangement of the azobenzene chromophore in the side chains was used to realize enantioselective polymerization and light-triggered reversible switching between opposite chirality for the PDA backbone.
