Side-Chain-Type Metallo-Macrocycles: η 5 -Cyclopentadienylcobalt-η 4 -cyclobutadiene-Incorporated Conjugated Macrocycle
Year: 2025
Type: article
Abstract: This work reports the synthesis of a 1,3-linked tetra-cyclopentadienylcobalt-cyclobutadiene macrocycle ( [CpCoCb] 4 ) via Pt-templated cyclization. Structural characterization by SC-XRD confirms a C i -symmetric nanohoop (1.5 nm diameter). Unique CH-π interactions drive 1D channel packing. Electrochemical studies reveal multi-redox activity. This work establishes a new paradigm for strained organometallic architectures with potential applications in multi-state molecular electronics and host-guest systems.
