Langmuir‐Blodgett (LB) monolayers with an extremely dense azobenzene moiety in a unit area, were prepared using a series of ionic liquid crystalline polymers (ILCPs) and their nonionic family (NLCPs). The isober curves and the compression‐expansion isotherms of the ILCPs and NLCPs on water showed that the polymer Langmuir monolayers have good quality. The molecular organization of these polymers on the water surface depended on the length of spacer alkyl chains and the existence of ammonium salts. Low‐molecular‐weight liquid crystals between the LCP monolayer dipped glass substrates showed a homeotropic alignment.
