Nanostructural analysis of self-standing pyrrole/2-formylpyrrole copolymer films

Self-standing pyrrole/2-formylpyrrole copolymer films with hierarchical nanostructures were successfully prepared without using a surfactant to clarify their self-assemble mechanism. The nanostructures by electron microscope techniques significantly provided well-defined and extended conjugation nanodomains that resulted in the structural color.

► Pyrrole films copolymerized with 2-formylpyrrole were prepared without a surfactant.
► The films were self-standing and had high mechanical properties.
► The films provided the structural color with high conductivity.
► The hierarchical nanostructures by self-assembly in the films were clarified.
► The structure was attributed to well-defined and extended conjugation nanodomains.
