Pyrene is a polycyclic aromatic hydrocarbon (PAH) composed of four fused benzene rings. It has a distinct aromatic odor, produced by incomplete combustion of organic matter. Pyrene exhibits strong fluorescence, emitting in the blue region of the spectrum, making it useful as a probe for studying molecular interactions in solution and on surfaces. Pyrene is also used as a model compound for the study of PAHs in various environments and biological systems because of its ubiquity in these environments. However, long-term exposure to pyrene has been associated with potential health risks, including carcinogenicity and mutagenicity.
Pyrene 是由四个稠合苯环组成的多环芳烃 (PAH)。它具有明显的芳香气味，由有机物不完全燃烧产生。Pyrene 表现出强烈的荧光，在光谱的蓝色区域发射，使其可用作研究溶液和表面分子相互作用的探针。Pyrene 也被用作研究各种环境和生物系统中多环芳烃的模型化合物，因为它在这些环境中无处不在。然而，长期接触 Pyrene 与潜在的健康风险有关，包括致癌性和致突变性。
