Here, we present two distinct systems exhibiting dynamic changes in structural, optical, and electrical properties. Firstly, we have demonstrated a multitude of responsive colors from a conjugated polymer film, arising from thin-film interference. This mechanism provides excellent control over the thin-film color by varying the film thickness, type of substrate, and degree of polaron population, and exhibit reversible color changes by oxidative or reductive environment with color responsivity controllable with the nature of the polaron state. Secondly, we have adopted a combination of bottom-up DNA-directed self-assembly and top-down photothermal patterning to fabricate free-standing nanoparticle films with vertical and lateral heterogeneity. We demonstrate that this approach provides a powerful means to generate dynamic nanostructures that can undergo complex and programmable shape transformation instructed by the lateral and vertical patterns inscribed in the film as well as the information carried in DNA
