| Outline of Final Research Achievements |
We fabricated ultra-thin films consisting of highly ordered π-conjugated functional groups. Carbazole-containing polymer pCzAA was prepared by free radical polymerization of amphiphilic monomer with amide groups. For the pCzAA, only a small amount (less than 20 mol%) of amphiphilic polymer, poly(N-dodecylacrylamide), (pDDA), which has long alkyl chains as a hydrophobic part, enhances the pCzAA monolayer stability. This high mixing ratio of pCzAA to pDDA (90 mol%) exceeds the percolation threshold in the two-dimensional plane (45 mol%), which assures a charge transport pathway in the in-plane direction. pCzAA:pDDA blend monolayers were transferred onto various substrates over 80 layers in high order. X-ray reflectivity measurements revealed that pCzAA:pDDA films had a highly ordered layered structure. Therefore, we conclude that the dimension control from 2D to 3D of π-conjugated unit nanoassemblies was realized by LB technique with acrylamide-based polymers with π-conjugated units.
