1,3,6,8-Tetrabromopyrene

Description:

1,3,6,8-Tetrabromopyrene is a polycyclic aromatic hydrocarbon (PAH) that has been extensively studied due to its brominated structure, which enhances its stability and potential applications in various fields. This compound is characterized by the presence of four bromine atoms attached to the pyrene backbone, which significantly alters its physical and chemical properties compared to non-brominated PAHs. It typically appears as a dark solid and is insoluble in water but soluble in organic solvents. The bromination increases its molecular weight and can influence its reactivity, making it of interest in studies related to environmental chemistry and toxicology. 1,3,6,8-Tetrabromopyrene is known for its potential use as a flame retardant, but it also raises concerns due to its persistence in the environment and potential bioaccumulation. Its toxicity and environmental impact are subjects of ongoing research, particularly regarding its effects on aquatic organisms and its role in the broader context of brominated flame retardants.

1,3,6,8-Tetrabromopyrene is a brominated derivative of pyrene. It has been shown to be chemically stable and does not react with fatty acids in the same way as other chemicals. 1,3,6,8-Tetrabromopyrene has been used in a study on luminescent probes for electrochemical studies. The probes were synthesized by coupling 1,3,6,8-tetrabromopyrene with an electron donor (e.g., 8-hydroxyquinoline) or acceptor (e.g., triethanolamine). The probe was then applied to a metal surface where it could be observed through electrochemical impedance spectroscopy. This chemical is also used as a functional theory to study the uptake of heavy metals onto polymer matrices. One example of this is when 1,3,6,8-tetrabromopyrene is doped into poly(vinylidene
