Abstract
The fine structures in the solid state and molecular orientation in Langmuir-Blodgett films of newly synthesized ternary comb copolymers with N-vinylcarbazole were investigated by wide-angle X-ray diffraction (XRD), small angle X-ray scattering, in-plane XRD, out-of plane XRD and atomic force microscopy. From the results of XRD in bulk, two kinds of short spacing peaks based on the formation of the sub-cell for fluorinated and hydrogenated side-chains were confirmed. Further, these ternary copolymers formed highly ordered layer structure. In addition, these ternary copolymers formed extremely condensed monolayers on the water surface. From the out-of plane XRD measurements of multilayers, formation of highly ordered layer structure was conformed. From the results of in-plane XRD and AFM, it was found that phase-separated structures between fluorinated and hydrogenated side-chains could not form in two-dimensional films. These structural changes may be cause by the interaction between the carbazole rings.
