The combination of redox-active ferrocene moieties, conju-gated B=N units, and p-phenylene building blocks in linearly concate-nated architectural arrangements has been explored. Oligo- and poly(ferrocenylene iminoborane)s have been successfully prepared, whereby in the latter case, the formation of linear polymers vs. dis-crete molecular macrocycles could be largely influenced by the poly-merization conditions applied. In addition, a series of well-defined co-oligomers composed of ferrocenylene and p-phenylene moieties bridged by one or two B=N units in all possible combinations have been prepared, many of which have been structurally characterized using single-crystal X-ray diffraction. Pendent triisopropylphenyl groups on boron provide pronounced kinetic stabilization. Polycon-densation of complementary monomers gave copolymers comprising alternating ferrocenylene and p-phenylene iminoborane building blocks, which were found to be cyclic in nature. UV-vis absorption spectroscopic and electrochemical studies provided highly valuable insights into the interaction of the different moieties over the B=N bonds, particularly, the electronic communication between the elec-troactive ferrocene units.
