Pyrene-4,5-dione (CAS: 6217-22-7) stands as a significant compound within organic chemistry, recognized for its distinctive molecular structure and broad applicability. As an oxidized polycyclic aromatic hydrocarbon (PAH) featuring a 1,2-dione functional group, this compound, also known by synonyms such as 4,5-Pyrenedione or Pyrene-4,5-quinone, serves as a crucial intermediate in the synthesis of various high-performance materials. Its molecular formula is C16H8O2, with a molecular weight of 232.23400 g/mol, highlighting its compact yet versatile nature.

The physical and chemical properties of Pyrene-4,5-dione are well-defined, making it a reliable choice for demanding chemical processes. It exhibits a melting point of approximately 310 °C, a boiling point of 467.6ºC at 760 mmHg, and a flash point of 202.2ºC. Its density is 1.433g/cm3, and it possesses a refractive index of 1.807. Typically presenting as a light yellow to yellow to orange powder or crystals, Pyrene-4,5-dione is ideally stored in a dry, cool, and sealed environment to prevent exposure to air and maintain its integrity and high purity, which is consistently over 97%.

One of the most notable applications of Pyrene-4,5-dione is its role as a key building block in the construction of Covalent Organic Frameworks (COFs). It acts as a 1,2-diketone bridging ligand linker, facilitating the formation of complex COF networks. These frameworks are gaining immense interest in organic electronic applications, including their use in optoelectronic devices due to their predictable structures and tunable properties. The integration of pyrene derivatives into these frameworks leverages the inherent photophysical properties of pyrene, such as its propensity for excimer formation and delayed fluorescence, which are vital for enhancing device performance.
