The relentless pursuit of innovation in electronic displays has brought Organic Light-Emitting Diodes (OLEDs) to the forefront, offering unparalleled visual experiences. The development of these advanced technologies hinges on the availability of specialized organic materials, and among them, precisely engineered molecules like 9-(4-Bromophenyl)-10-(1-Naphthalenyl)Anthracene (CAS 1160506-32-0) play a crucial role. This article explores the chemical properties and significant applications of this key OLED intermediate, providing insights for researchers and industry professionals looking to purchase or understand its value.

Chemical Identity and Structure

9-(4-Bromophenyl)-10-(1-Naphthalenyl)Anthracene, with the molecular formula C30H19Br and a molecular weight of approximately 459.38 g/mol, is characterized by its anthracene core. This core structure is substituted at the 9-position with a 4-bromophenyl group and at the 10-position with a 1-naphthalenyl group. This specific arrangement of functional groups is not arbitrary; it is designed to imbue the molecule with desirable electronic and photophysical properties necessary for OLED device operation. The presence of bromine also provides a convenient handle for further synthetic modifications, making it a versatile building block.

Key Chemical Properties and Specifications

For practical application in the demanding OLED industry, precise specifications are paramount. 9-(4-Bromophenyl)-10-(1-Naphthalenyl)Anthracene is typically supplied as a white to yellow crystalline powder. Crucially, its purity level is a critical parameter, with most suppliers guaranteeing a minimum assay of ≥98.0%, often verified by HPLC. This high level of purity is essential to prevent interference with charge transport and light emission processes within the OLED device. Its physical form and stability, when stored correctly in cool, ventilated conditions, further contribute to its reliability as a procurement option.

Applications in OLED Technology

The primary application for 9-(4-Bromophenyl)-10-(1-Naphthalenyl)Anthracene is as an intermediate in the synthesis of advanced materials for OLED displays. It can serve in various roles within the OLED stack, including:

  • Host Materials: Contributing to the emissive layer, often in conjunction with dopant emitters, to facilitate efficient energy transfer and light generation.
  • Charge Transport Materials: Assisting in the smooth movement of electrons or holes within the device, thereby improving overall efficiency and reducing operating voltage.

The unique electronic structure provided by its anthracene, phenyl, and naphthyl components makes it an effective material for achieving high brightness, good color purity, and extended device lifetimes. Manufacturers looking to buy this compound can expect it to be a foundational element in developing next-generation display technologies.

Sourcing and Quality Assurance

When procuring 9-(4-Bromophenyl)-10-(1-Naphthalenyl)Anthracene, it is vital to partner with established OLED material suppliers or manufacturers. These suppliers ensure that the material's chemical properties, including its high purity, are consistently maintained through rigorous quality control. Understanding the CAS number (1160506-32-0) and the guaranteed assay is the first step for any procurement manager or scientist looking to integrate this important intermediate into their product development cycle.
