Two blends (1:1 and 5:3 w:w) of poly(2-vinylpyridine) (PVP) and partly brominated polystyrene were spin-cast (with constant inherent domain scale 2R = 4.2 +/- 0.5 mu m) onto a gold substrate which had been microcontact printed with stripes of hexadecanethiol SAM. Two chemical patterns on the substrate were used, one with symmetrical stripes (4 mu m Au/4 mu m hexadecane SAM) and the other with narrow gold stripes and wider SAM stripes (3 mu m/5 mu m). The resulting film morphologies were mapped with atomic force microscopy. Secondary ion mass spectrometry shows that raised regions on the film surface correspond to PVP-rich domains, and the surface polymer composition extends all the way down to the substrate. Fourier analysis reveals structural modes (lambda/n) smaller than the pattern periodicity lambda = 8 mu m. PVP preferentially adsorbs to the gold regions of the pattern. For the asymmetric pattern, which has a relatively small Au area interacting with the PVP, the fundamental mode (n = 1) is extinguished and higher-order substructures (n > 1) are seen. Use of a PVP-rich blend increases the intensity of the n = 3 mode and reduces that of the n = 2 mode. When both blend and pattern were asymmetric, both lambda/2- and lambda/3-substructures were observed, and the fundamental pattern periodicity was extinguished.
