It is demonstrated with four representative examples that the dimers of benzo[b]quinolizinium, dibenzo[b,g]quinolizinium and anthracene derivatives may be used as a source to release the DNA‐binding monomers upon irradiation in the presence of DNA, as determined by monitoring the reaction with absorption and CD spectroscopy. Specifically, the dimers of the benzo[b]quinolizinium turned out to be suitable for this purpose as the ligand is formed rapidly in the presence of DNA and subsequently intercalates into the nucleic acid. In combination with the promising biological properties and bioanalytical value of benzo[b]quinolizinium derivatives, this approach may be used as a general method to generate these functional dyes with spatio‐temporal control.

从苯并[b]喹啉鎓和蒽衍生物的[4 + 4]二聚体光诱导释放DNA结合配体。

通过四个有代表性的例子证明，苯并[ b ]喹啉鎓，二苯并[ b，g ]喹啉鎓和蒽衍生物的二聚体可以用作在存在DNA的情况下经辐照释放出DNA结合单体的来源。通过吸收和CD光谱监测反应。具体地，证明苯并[ b ]喹啉鎓的二聚体适合于该目的，因为在DNA存在下迅速形成配体，随后插入核酸中。结合有希望的苯并[ b]的生物学特性和生物分析价值] quinolizinium衍生物，此方法可用作生成时空控制的这些功能性染料的通用方法。
