We have synthesized four indole derivatives (INS1, IND1, INS2 and IND2) successfully, and experimental results of biochemical RNA fluorescence assays and direct intracellular imaging demonstrated that they are potential highly RNA-selective fluorescent turn-on probes possessing good counterstain compatibility with the classic DNA-staining dye DAPI. Moreover, these sensors exhibit large two-photon excited fluorescence action absorption cross-section in the presence of RNA and are also capable of imaging intracellular RNA in two-photon fluorescence microscopy.
