Description

General description

Bis(pentamethylcyclopentadienyl)cobalt(II) is a powerful electron donor that is widely used as a dopant to prepare molecular semiconductors due to its low solid-state ionization energy (3.3 eV). The dopant improves charge injection and transport in electronic devices.[1]

Application

Bis(pentamethylcyclopentadienyl)cobalt(II) can be used as:

• An n-type dopant to fabricate organic electronic materials such as copper phthalocyanine thin films.[1]
• A reducing agent to synthesize high-quality reduced graphene oxide thin films at room temperature.[2]
• A metal organic precursor for plasma-enhanced atomic layer deposition of cobalt.[3]
