The Cover Feature shows a 2D hexagonal mesostructured electroactive film obtained through layer‐by‐layer assembly of (ferrocenylmethyl)hexadecyldimethylammonium bromide, a redox surfactant, and poly(acrylic acid). The picture also includes an experimental GISAXS pattern of the mesostructured film. By using ferrocene‐appended surfactants as structural and functional units, the formation of robust electroactive mesostructured films can be achieved. More information can be found in the Communication by O. Azzaroni, F. Battaglini, and co‐workers (DOI: 10.1002/cplu.202000358).

通过氧化还原表面活性剂和聚电解质的逐层组装形成介电结构的电活性薄膜

封面特征显示了二维六方晶介电活性膜，该膜是通过（二茂铁基甲基）十六烷基二甲基溴化铵，氧化还原表面活性剂和聚丙烯酸的逐层组装获得的。图片还包括介孔结构膜的实验性GISAXS模式。通过使用添加二茂铁的表面活性剂作为结构和功能单元，可以形成坚固的电活性介观结构膜。有关更多信息，请参见O. Azzaroni，F。Battaglini及其同事的通讯（DOI：10.1002 / cplu.202000358）。
