We present a perfluorocarbon-hydrocarbon amphiphilic cyanine dye that J-aggregates in fluorous solvent. J-Aggregation is a special type of fluorophore aggregation, affording enhanced photophysical properties. Cyanine dyes are excellent J-aggregators in water but, until now, cyanine J-aggregates have not been translated to nonaqueous media. The fluorous phase J-aggregate displays enhanced photostability and processability compared to analogous aqueous aggregates.
我们提出了一种全氟碳-碳氢两亲性菁染料，它在氟溶剂中形成 J 聚集体。J 聚集体是一种特殊类型的荧光团聚集，赋予了增强的光物理性质。菁染料在水中是极好的 J 聚集体，但到目前为止，菁 J 聚集体还没有被转化为非水介质。与类似的水相聚集体相比，氟相 J 聚集体具有增强的光稳定性和加工性能。
