Abstract
AbstractThe self‐assembly of block copolymers (BCPs) into photonic materials has drawn significant attention due to the flexibility and diversity of the building blocks that can be synthesized. This review provides a brief overview of the development of this research area and then discusses in detail recent advances in the use of BCPs as photonic pigments. In particular, the role of confinement upon the self‐assembly process to form well‐ordered lamellae is described and compared to correlated disordered structures derived from densely packed micelles. These systems respectively act as 1D (multilayered) photonic crystals and photonic glasses and are here critically compared in terms of their structural characteristics and optical performance. Finally, based on this understanding, the current challenges in this field are discussed and the potential for future developments is explored.
Highlights
Block copolymers (BCPs) are an interesting class of material that has been proven effective in fabricating photonic materials due to their capability to self-assemble into structures on the scale of the wavelength of visible light
We first provide an overview of the photonic structures that can be formed from block copolymers via a self-assembly pathway
This spacing typically increases with the overall degree of polymerization (DP) of the BCPs within a polymer series of the same monomer composition.[143,144,145,146]
