Pyrene is one of the simplest polyaromatic hydrocarbons (PAHs). Pyrene derivatives are known for their ability to intercalate dsDNA.

Pyrene possesses intrinsic fluorescence. When two pyrene residues are located in close proximity, excimer formation can be observed by fluorescence spectroscopy. Pyrene has been therefore used to probe structures of biomolecules.

Ethynylpyrene molecule contains terminal triple bond fragment for Click Chemistry, as well as other coupling reactions such as Sonogashira coupling.

Pyrene 是最简单的多环芳烃 (PAHs) 之一。 Pyrene 衍生物以其嵌入 dsDNA 的能力而闻名。

Pyrene 具有固有荧光。 当两个Pyrene 残基非常接近时,可以通过荧光光谱观察到准分子的形成。 因此,Pyrene 已被用于探测生物分子的结构。

乙炔基芘分子包含用于 Click Chemistry 的末端三键片段,以及其他偶联反应,例如 Sonogashira 偶联。
