Langmuir‐Blodgett (LB) films consisting of the hybrid of a polymer having the azobenzene (Az) side chain and 4î‐pentyl‐4‐cyanobiphenyl (5CB) are prepared. Microscopic observations and spectroscopic data both indicate that the Az side chain and 5CB are homogeneously mixed at a molecular level without phase separation in the layer. This provides a satisfactory model of the command surface system. Time course accumulation of spectroscopic data for multilayered hybrid films reveals the cooperative nature of the photo‐motivated molecular motions.
