quantum yield than that of AZSiR-1. However, the photostability of the AZSiR-2 probe becomes poor. By changing the substituent groups from methyl to trifluoromethyl, the AZSiR-3 probe displays slightly red-shifted absorption and emission peaks, and good photostability. Furthermore, the bulky groups on the phenyl ring of Si-rhodamine prevent nucleophilic attack through steric hindrance, and endow Si-rhodamine

The invention relates to novel caging-group-free photactivatable fluorescent dyes having the structural formula (I) as well as to the corresponding photoactivated fluorescent dyes having the structural formula (II). The invention further relates to the use of the photoactivatable compounds as such or after photoactivation, in particular as fluorescent tags, analytical reagents and labels in optical microscopy, imaging techniques, protein tracking, nucleic acid labeling, glycan analysis, capillary electrophoresis, flow cytometry or as a component of biosensors, or as analytical tools or reporters in microfluidic devices or nanofluidic circuitry.
