Side-Chain-Type Metallo-Macrocycles: η<sup>5</sup>-Cyclopentadienylcobalt-η<sup>4</sup>-cyclobutadiene-Incorporated Conjugated Macrocycle
This work reports the synthesis of a 1,3-linked tetracyclopentadienylcobalt-cyclobutadiene macrocycle (<b>[CpCoCb]</b><sub><b>4</b></sub>) via Pt-templated cyclization. Structural characterization by SCXRD confirms a <i>C</i><sub><i>i</i></sub>-symmetric nanohoop (1.5 nm diameter). Unique CH-π interactions drive the 1D channel packing. Electrochemical studies reveal multiredox activity. This work establishes a new paradigm for strained organometallic architectures with potential applications in multistate molecular electronics and host-guest systems.
