7-nitroindoline compounds are disclosed that comprise a triplet sensitising group such as substituted or unsubstituted benzophenone group and can be used to cage effector species. In particular, the inclusion of a triplet sensitising group linked to the 4 or 5 position of a 7-nitroindoline derivative provides compounds which can be photolysed to release the effector species with unexpectedly enhanced photolysis efficiency. The triplet sensitising group may be linked directly to the 7-nitroindoline or via a spacer group. In some examples, the triplet sensitising group and/or the spacer group can be selected to enhance other properties of the caged compound such as its solubility, spectroscopic properties or stability (e.g. stability of the linkage between the nitroindoline moiety and the triplet sensitiser). This can help to improve the performance of the caged compound, especially in aqueous environments containing dissolved oxygen.
本文介绍了一种包含三重敏化基团的7-硝基吲哚化合物,例如取代或未取代的苯基酮基团,并可用于封闭效应物种。特别是,将三重敏化基团连接到7-硝基吲哚衍生物的4或5位上,可提供可光解化合物,其光解效率意外增强,从而释放效应物种。三重敏化基团可以直接连接到7-硝基吲哚或通过间隔基团连接。在某些示例中,可以选择三重敏化基团和/或间隔基团以增强封闭化合物的其他性质,例如其溶解性,光谱性质或稳定性(例如硝基吲哚基团和三重敏化剂之间的连接的稳定性)。这有助于提高封闭化合物的性能,特别是在含有溶解氧的水环境中。
