N,N'-Bis(2-ethylhexyl)-3,4,9,10-perylenetetracarboxylic Diimide, commonly abbreviated as PDI26 and identified by CAS number 82531-03-1, is a sophisticated organic semiconductor material that plays a vital role in the advancement of modern electronics. As a derivative of perylene, PDI26 inherits the exceptional photophysical stability and strong absorption characteristics of its parent molecule, while the addition of ethylhexyl side chains significantly enhances its solubility and processability in common organic solvents. This combination of properties makes it highly desirable for applications requiring thin-film deposition, such as Organic Light-Emitting Diodes (OLEDs), Organic Field-Effect Transistors (OFETs), and Organic Photovoltaics (OPVs).

The molecular formula of PDI26 is C40H42N2O4, with a molecular weight of approximately 614.77 g/mol. Its physical form is typically a solid, often appearing as a crystalline powder. The key to its efficacy in electronic devices lies in its electronic structure, which allows for efficient electron transport, classifying it as an n-type semiconductor. This characteristic is indispensable for creating balanced charge carrier injection and transport in devices like OLEDs and for enabling the functionality of n-channel transistors in OFETs. The minimum purity required for these applications is generally 97%, underscoring the importance of precise synthesis and purification protocols employed by manufacturers.

The manufacturing process for PDI26 involves complex chemical reactions, typically starting with perylene-3,4,9,10-tetracarboxylic dianhydride and reacting it with 2-ethylhexylamine. Subsequent purification steps, such as recrystallization or sublimation, are critical to achieve the high purity levels demanded by the electronics industry. For B2B buyers, understanding these manufacturing insights helps in appreciating the value of high-purity PDI26 and the importance of selecting a supplier that masters these processes. When you buy PDI26, you are investing in a material that has undergone rigorous chemical engineering.

The significance of PDI26 extends to its role as a building block for more complex functional materials used in cutting-edge technologies. Its consistent availability and quality from reputable manufacturers, particularly from specialized chemical suppliers in China, ensure that innovation in organic electronics can continue to progress. Whether for research and development or for industrial-scale production, securing a reliable supply of high-purity PDI26 is a strategic decision that directly impacts the performance and success of the final electronic products.
