Overview
A self-assembled hybrid material demonstrating a photonic bandgap in the visible wavelength regime can be tuned thermally or electrically. Hydrogen bonds between a host polymer and liquid-crystal-mesophase-forming moieties guest units to form a self-assembled 1D lamellar structure with a 175nm periodicity. It provides a stop-band in the green wavelength regime.
Results and Discussion
Hydrogen bonds induces the formation of a liquid-crystal mesophase in a block of a coil-coil diblock copoloymer host. Anionic synthetization of polysterene-block-poly(methylacrylicacid) (PS-b-MAA) bloch-copolymer self-assembles.
