Abstract

The directed self-assembly of 3-miktoarm star terpolymer chains (polyisoprene-arm-polystyrene-arm-polyfer-rocenylethylmethylsilane (3 mu-ISF)) into 2D Archimedean filings is described. A morphological change from (4.8(2)) to (6(3)) tiling is reported in the 3 mu-ISF thin film blended with PS hornopolymer when a greater swelling of PI is achieved during the solvent annealing process. Highly oriented (4.8(2)) tilings were produced by templating the self-assembled three colored structures in blended thin films. The use of (4.8(3)) and (6(3)) tilings as nanolithographic masks to transfer square and triangular hole arrays into the substrate is also demonstrated.
