General description

Bis(cyclopentadienyl)cobalt(II) also known as cobaltocene, is an organometalliccompound that is widely used in the field of polymer synthesis, cobaltnanomaterials, and redox flow batteries.

Application

Bis(cyclopentadienyl)cobalt(II) can be used:
  • As a dopant to prepare encapsulated carbon nanotubes with high thermoelectric conversion efficiency.
  • As a CVD precursor to fabricate cobalt oxide thin films for various applications.
  • As a redox-active anode species in Li-based redox flow batteries to achieve higher energy densities and energy efficiencies.
  • As a catalyst for controlled/“living” radical polymerization of methylmethacrylate.
