Abstract Using the alternating layer-by-layer (LBL) assembly technique, ultrathin polyelectrolyte multilayers with azobenzene-containing bolaamphiphiles or ionenes were prepared. In the initial films the orientational distribution of the azobenzene units is azimuthally isotropic, but a small out-of-plane orientation was found. Except for the photo-inert sample of polyethyleneimine/4,4′-disulfatohexyloxyazobenzene 1, a Z-rich steady state was always established upon UV irradiation. The… CONTINUE READING
