- Fluorescent dye, preparation method and applications thereof
-
The invention belongs to the technical field of organic synthesis, and particularly relates to a fluorescent dye, a preparation method and applications thereof, wherein the fluorescent dye has a structural general formula represented by a formula I defined in the specification, X and Y are the same or different O, S, C(CH3)2 or NR6, R2 and R3 are the same or different hydrogen or functional groups, R1, R4, R5 and R6 are all functional groups, and Z is a negative ion. According to the present invention, the fluorescent dye has living cell membrane permeability, can be used for fluorescence imaging of living cell microstructures, and can obtain STED super-resolution fluorescence imaging, laser confocal imaging and other fluorescence imaging of living cells.
