Understanding Tetracene Derivatives

Tetracene, an aromatic hydrocarbon, is part of the polycyclic aromatic hydrocarbon (PAH) family. Its derivatives, such as 5,12-bis(2-phenylethynyl)tetracene (CAS: 18826-29-4), are formed by chemically modifying the basic tetracene structure. In this specific compound, two phenylethynyl groups are attached to the tetracene core at the 5 and 12 positions. This modification significantly alters its electronic structure, influencing its photophysical properties and overall performance in advanced applications.

The chemical identity of 5,12-bis(2-phenylethynyl)tetracene is defined by its CAS number 18826-29-4. Its molecular formula is C34H20, with a molecular weight of approximately 428.52 g/mol. Typically appearing as a white to off-white powder, it is recognized for its stability and its utility as a building block for more complex molecular architectures.

Applications in Materials Science and Organic Electronics

The extended pi-conjugation system within 5,12-bis(2-phenylethynyl)tetracene makes it a candidate for various advanced materials applications:

  • Organic Light-Emitting Diodes (OLEDs): Compounds with similar structures are explored for their emissive properties in OLED displays and lighting. The phenylethynyl groups can help tune the emission color and efficiency.
  • Organic Semiconductors: The delocalized electrons in the conjugated system are fundamental to its potential use as an organic semiconductor in field-effect transistors (OFETs) and photovoltaic devices.
