The Chemistry Behind [70]PCBM: Properties and Synthesis Insights for Researchers
The progress in organic electronics owes much to the intricate chemistry and precise engineering of semiconductor materials. Among these, fullerene derivatives like (6,6)-Phenyl C71 Butyric Acid Methyl Ester, known as [70]PCBM, play a pivotal role. With its unique chemical structure and electronic characteristics, [70]PCBM (CAS: 609771-63-3) has become a benchmark material, particularly in the development of high-performance organic solar cells (OSCs) and organic field-effect transistors (OFETs).
Chemically, [70]PCBM is a functionalized fullerene, a derivative of C70 fullerene where a phenylbutyric acid methyl ester group is attached. This modification imparts crucial properties, most notably enhanced solubility in organic solvents and a broadened absorption spectrum compared to its C60 counterparts. The C70 fullerene cage itself provides a robust framework for electron acceptance and transport. The molecular formula is C82H14O2, with a molecular weight of approximately 1031 g/mol.
In organic solar cells, [70]PCBM functions as an n-type electron acceptor. It is typically blended with electron-donating polymers, forming a bulk heterojunction (BHJ) active layer. The synergy between the donor and acceptor materials is critical for efficient photovoltaic performance. [70]PCBM's ability to efficiently accept electrons from the donor and transport them to the electrode, coupled with its favorable energy levels, contributes significantly to achieving high power conversion efficiencies (PCE). Its stronger absorption in the visible region means it can capture a broader range of the solar spectrum, thereby increasing the total amount of light converted into electricity.
For researchers and manufacturers, understanding the synthesis and purification of [70]PCBM is key to achieving optimal device performance. While synthesis pathways can be complex, the availability of high-purity [70]PCBM from reliable suppliers like NINGBO INNO PHARMCHEM CO., LTD. in China is essential. We provide this critical material at competitive prices, ensuring that scientific advancements are supported by top-tier chemical inputs. This focus on quality is vital for reproducible results in organic electronic device fabrication.
The chemical properties of [70]PCBM—its semiconducting nature, solubility, and optical characteristics—make it an indispensable component for innovation in organic electronics. Whether designing next-generation solar cells or advanced transistors, the molecular architecture of [70]PCBM offers a distinct advantage.
