Cover Feature: Poly(Ferrocenylene Iminoborane) and the Merging of 1,1’‐Ferrocenylene with <i>p</i>‐Phenylene Iminoborane Building Blocks into Alternating Copolymers, Oligomers, and Macrocycles (Chem. Eur. J. 18/2025)

The Cover Feature shows oligomers and polymers containing redox-active ferrocene moieties, BN units and p-phenylene building blocks, which are represented by the three vessels. Cyclic and linear polymers were obtained from polycondensation reactions. Electrochemical and photophysical investigations provided valuable insights into the interactions of the building blocks and the electronic communication between the ferrocene units.
