Cyanines are one of the few kinds of molecules whose absorbance and emission can be shifted in a broad spectral range from the ultraviolet to the near infrared. They can easily transform into J-aggregates with narrow absorption and emission peaks, along with a redshift in their spectra. This mini-review presents cyanine dyes and their J-aggregates and discusses their structure and spectral properties that illustrate their specificities. We summarize the theoretical and experimental state of the art on cyanine J-aggregates and their applications, also laying the groundwork for cyanine J-aggregates synthesis and characterization methods.
菁染料是为数不多的能在从紫外到近红外的宽光谱范围内实现吸收和发射移动的分子之一。它们很容易形成具有窄吸收和发射峰以及光谱红移的 J-聚集体。这篇迷你综述介绍了菁染料及其 J-聚集体，并讨论了它们的结构和光谱性质，说明了它们的特异性。我们总结了菁 J-聚集体及其应用的理论和实验现状，也为菁 J-聚集体的合成和表征方法奠定了基础。
