Abstract

Langmuir monolayers and multilayered Langmuir-Blodgett (LB) films of main chain liquid crystal polymers (MCLCPs) having 1,4-bisstyrylbenzene (BSB) groups and polyoxyethylene (POE) chains were prepared. The properties of monolayers at an air-water interface can be related to the characteristics of these polymers in the bulk LC phase. The multilayered structure of the LB film is consistent with that of the smectic LC phase. In the layer, the BSB groups form the H-aggregated structure and the POE chains form the hair-pin loops.
