The chromophore alignment was analyzed on the basis of the polarized UV-visible spectra: the tilt angle of the transition moment of trans-azobenzene with respect to the surface normal was determined to 64 +/- 2 degrees, indicating a strong trend for chromophores in the multilayered films to planar alignment.
