(Color online) (Top) Chemical structure of p(DDA/DR1), pDDA, and p(DDA/Vpy). (Bottom) Schematic illustration of a hybrid nanoassembly structure.
(Color online) Polarized second harmonic light interference patterns as a function of angle of incidence; one-bilayer p(DDA/DR1)/pDDA nanosheets with two-layer p(DDA/Vpy) nanosheets before (dashed line) and after (solid line) immersion in a gold nanoparticle aqueous solution for . For the layer structure, see the bottom of Fig. 1.
(Color online) (a) UV-vis absorption spectra of hybrid nanoassemblies as a function of immersion time. (b) Second harmonic light intensity from hybrid polymer nanoassemblies and the absorbance at as a function of immersion time. The SH light intensity was normalized with the intensity of the sample before immersion at an incident angle of 45°.
(Color online) ESEM image of gold nanoparticles immobilized on p(DDA/Vpy) nanosheets after immersion. The detail of the layer structure is shown in Fig. 1. (Inset) ESEM image obtained from the magnification of the top middle white rectangle.
