Facile access to complex systems is crucial to generate the functional materials of the future. Herein, we report self-organizing surface-initiated polymerization (SOSIP) as a user-friendly method to create ordered as well as oriented functional systems on transparent oxide surfaces. In SOSIP, self-organization of monomers and ring-opening disulfide exchange polymerization are combined to ensure the controlled growth of the polymer from the surface. This approach provides rapid access to thick films with smooth, reactivatable surfaces and long-range order with few defects and high precision, including panchromatic photosystems with oriented four-component redox gradients. The activity of SOSIP architectures is clearly better than that of disordered controls.
方便地获取复杂体系对于生成未来的功能材料至关重要。在此，我们报告了自组织的表面引发聚合（SOSIP），这是一种在透明氧化物表面上创建有序和定向功能体系的用户友好方法。在 SOSIP 中，单体的自组织和开环二硫键交换聚合相结合，以确保从表面控制聚合物的生长。这种方法可以快速获得具有光滑、可重新激活表面的厚膜，以及具有低缺陷和高精度的长程有序，包括具有定向四组分氧化还原梯度的全光谱光系统。SOSIP 结构的活性明显优于无序对照物。
