We have newly constructed "multi-particle layered organization" of aromatic polyamide(poly-(N-alkylated benzamide), abbrev. PABAn, n : carbon number of side-chains) derivatives having both a rigid main chain and a flexible side chains by a Langmuir-Blodgett (LB) technique. This organization is composed of the build-up particle layers with highly regular arrangement along the c-axis. The particle arrangement of this organization of polymer nanosphere was estimated by performing out-of plane X-ray diffraction (XRD), and atomic force microscopic (AFM) observation. In addition, it is also proposed that ternary comb copolymers with carbazole units and both hydrogenated and fluorinated side-chains are candidates of newly typed "polymer nanosheet" material. These copolymers with high hydrophobic carbazole contents also formed single particle layer at air/water interface and "multi-particle layered organization" was constructed by a LB technique. Therefore, it was found that "multi-particle layered organization of polymer nanosphere" and "polymer nanosheet" are simultaneously formed by same component copolymer materials with hydrophobic carbazole units.
