Block-copolymer self-assembly has proven to be an effective route for the fabrication of photonic films and, more recently, photonic pigments. However, despite extensive research on this topic over the past two decades, the palette of monomers and polymers employed to produce such structurally colored materials has remained surprisingly limited. In this Scientific Perspective, the commonly used block-copolymer systems reported in the literature are summarized (considering both linear and brush architectures) and their use is rationalized from the point of view of both their historical development and physicochemical constraints. Finally, the current challenges facing the field are discussed and promising new areas of research are highlighted to inspire the community to pursue new directions.
嵌段共聚物自组装已被证明是制备光子薄膜以及最近的光子颜料的有效途径。然而，尽管在过去二十年里对这一主题进行了广泛研究，但用于生产此类结构色材料的单体和聚合物种类仍然惊人地有限。在这篇《科学展望》中，总结了文献中报道的常用嵌段共聚物体系（考虑线性和刷状结构），并从其历史发展和物理化学限制的角度对它们的用途进行了合理分析。最后，讨论了该领域目前面临的挑战，并强调了有前景的新研究领域，以激励该领域探索新的方向。
