Polydopamine (PDA) is of interest as a mimetic material of melanin to produce structural color materials. Herein, to investigate the influence of the material composition of the artificial melanin particles on structural color, we demonstrated the preparation of core–shell particles by polymerization of norepinephrine or 3,4-dihydroxyphenylalanine, which are melanin precursors similar to dopamine, in the presence of polystyrene particles. It was revealed that the arrays of the prepared particles produce high-visibility structural color because of absorption of scattering light. Although poly(3,4-dihydroxyphenylalanine) showed the same tendency as PDA which was previous studied, polynorepinephrine can easily produce a smooth and thick shell layer compared with that of PDA, and pellets consisting of the particles showed angle-dependent structural color. Therefore, the artificial melanin particles that produce angle-dependent structural color became stable than ever before. These results indicated that material compositions of artificial melanin particles have influence on structural color, and an important finding for application as a coloring material was obtained.

黑色素前体对人造黑色素颗粒的结构颜色的影响：PolyDOPA，polydopamine和polynorepinephrine
聚多巴胺（PDA）作为黑色素的模拟材料以生产结构彩色材料而受到关注。在本文中，为了研究人造黑色素颗粒的材料组成对结构颜色的影响，我们证明了在存在下，通过去甲肾上腺素或3,4-二羟基苯基丙氨酸（类似于多巴胺的黑色素前体）的聚合制备核-壳颗粒聚苯乙烯颗粒。已经发现，由于吸收了散射光，所制备的颗粒的阵列产生了高可见性的结构颜色。尽管聚（3,4-二羟基苯丙氨酸）的趋势与先前研究的PDA相同，但与PDA相比，聚去甲肾上腺素可轻松产生光滑且厚实的壳层，由颗粒组成的颗粒显示出与角度相关的结构颜色。因此，产生依赖于角度的结构颜色的人造黑色素颗粒变得比以往任何时候都稳定。这些结果表明，人造黑色素颗粒的材料组成对结构颜色有影响，并且获得了用作着色材料的重要发现。
