我们报告了一种新的，简单的策略，应用蜂窝膜的图案化的胶体颗粒。通过自下而上的呼吸图方法和基于二茂铁基的低聚物的蜂窝膜的电化学性质的组合，已经制造了涂覆有0 D和1D-Ag纳米颗粒（NPs）的环状图案的高度有序的杂化膜。一个有趣的现象是，银点的成核和吸附优先发生在微孔的边缘。该杂化膜对碘酸盐的还原具有良好的电化学活性，并能有效地促进有机染料的催化还原。我们相信，这种方法可以用来装饰和/或组装功能性金属纳米粒子，如Au，Pd和Cu的蜂窝图案化的材料上的光子学，传感器和催化的进一步应用。
We report a new, simple strategy to apply honeycomb films for the patterning of colloidal particles. By combination of a bottom-up breath figure method and the electrochemical properties of the honeycomb films of ferrocenyl-based oligomers, highly ordered hybrid membranes coated with ring-like patterning of 0D- and 1D-Ag nanoparticles (NPs) have been fabricated. One interesting phenomenon is that the nucleation and adsorption of Ag dots occurred preferentially at the edges of the micropores. The hybrid membranes exhibited richly electrochemical activities towards reduction of iodate and enhanced effectively catalytic reduction of organic dyes. We believe that this method can be used to decorate and/or assemble functional metal NPs such as Au, Pd, and Cu on honeycomb-patterned materials for the further applications of photonics, sensors, and catalysis.
