In the realm of advanced materials for organic electronics, fullerene derivatives have carved out a significant niche. Among these, [6,6]-Phenyl-C61-butyric acid methyl ester, or PC61BM (CAS 160848-22-6), stands out due to its unique chemical properties and critical role in devices like organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Understanding its synthesis and properties is key for researchers and manufacturers seeking to leverage its potential.

Chemical Structure and Key Properties of PC61BM

PC61BM is a derivative of Buckminsterfullerene (C60), where a phenyl group and a butyric acid methyl ester moiety are attached to one of the carbon cages. The molecular formula is C72H14O2, with a molecular weight of approximately 910.88 g/mol. The addition of the functionalized side chain imparts crucial solubility in common organic solvents such as chlorobenzene, toluene, and o-dichlorobenzene. This solubility is paramount, allowing PC61BM to be processed from solution, which is essential for fabricating thin films through techniques like spin-coating or printing.

Key properties include:

  • Appearance: Typically a black powder.
  • Electron Affinity: High electron affinity, making it an excellent electron acceptor.
  • Electron Mobility: Possesses high electron mobility, vital for efficient charge transport in semiconductor devices.
  • Thermal Stability: Exhibits good thermal stability, contributing to device longevity.
  • Melting Point: Reported around 292°C, indicating its solid-state stability.

Synthesis Routes for PC61BM

The synthesis of PC61BM typically involves the functionalization of C60 fullerene. Common methods include the reaction of C60 with phenyl-substituted tosylhydrazones or other suitable precursors under specific reaction conditions, often involving solvents like 1,2-dichlorobenzene and catalysts or bases. The regioselectivity of the addition to the fullerene cage is also an important aspect, with the [6,6] isomer generally being preferred for optimal electronic properties. Manufacturers continuously refine these synthesis routes to improve yield, purity, and cost-effectiveness, ensuring a reliable supply of this advanced material.
