      abstract     = {Herein we report the preparation and characterization of
                      dendronized supramolecular polymers composed of a
                      carboxy-terminated azodendron, dAZO, and two different
                      vinylpyridine-containing polymers: poly(4-vinylpyridine)
                      (P4VP) and polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP)
                      block copolymer. P4VP can selectively complex dAZO through
                      hydrogen-bonding interactions, thus resulting in liquid
                      crystalline materials. Additionally, this strategy is also
                      applicable to the preparation of dendronized supramolecular
                      block copolymers (BCs). Lamellar, cylindrical, and spherical
                      morphologies are observed for the BC complexes depending on
                      the dAZO to vinylpyridine repeating unit ratio. Photoinduced
                      orientation of the azobenzene moieties is obtained in films
                      of the H-bonded materials—both P4VP and PS-b-P4VP based
                      complexes—by using 488 nm linearly polarized light and
                      characterized through birefringence and dichroism
                      measurements. High and stable values of birefringence are
                      obtained for polymers with azobenzene content as low as 2.7
                      wt $\%,$ thus demonstrating the benefits of preorganization
                      in photoactive dendritic moieties in side-chain H-bonded
                      materials.},
