Herein, we reported a simple, fast, and quantitative theoretical descriptor ΔGC-O that allows accurate predictions of a wide range of spontaneously blinking rhodamines. ΔGC-O denotes the Gibbs free energy differences between the closed and open forms of rhodamines and has a good linear relationship with experimental pKcycl values. This correlation affords an effective guide for the quantitative designs of spontaneously blinking rhodamines and eliminates trial-and-error. We have validated the predictive power of ΔGC-O via the development of two spontaneously blinking rhodamines of different colors and enhanced brightness. We also demonstrated their super-resolution imaging utilities in dynamic live-cell imaging. We expect that ΔGC-O will greatly facilitate the efficient creations of spontaneously blinking fluorophores and aid the advancements of super-resolution bioimaging techniques.

The invention provides self-flickering super-resolution fluorescent dye based on an SNAP-tag technology and synthesis and application thereof. The structure (1) of the fluorescent dye is shown in thespecification, intramolecular rotation of silicon rhodamine is inhibited by introducing azetidine, and therefore the fluorescent dye has the characteristics of high light stability, high quantum yieldand the like. Because of thermodynamic equilibrium of intramolecular spiralization of the dye, the fluorescent dye can flicker continuously and is further applied to super-resolution fluorescence imaging. In addition, the probe can be used for specifically labeling multiple target proteins fused with SNAP-tag labels in living cells, so that the tracing of the target proteins in the living cells is realized. The SNAP-tag self-flickering super-resolution fluorescent dye provided by the invention has wide application in the fields of protein labeling, protein-protein interaction, super-resolution fluorescence imaging and the like.

The invention provides a self-flickering fluorescent dye for super-resolution fluorescence imaging as well as synthesis and application thereof. According to the dye, azetidine is introduced into the4,5-sites of silicon rhodamine to inhibit intramolecular rotation, so that the characteristics of high quantum yield and high stability are achieved; meanwhile, under normal physiological conditions,fluorescence and non-fluorescence forms of the probe can be mutually converted through intramolecular interaction, so that the probe can be applied to living cell super-resolution imaging, the structural formula of the probe is shown as (1), and the dye can be combined with an antibody to perform specific labeling imaging on tubulin in cells. The dye can be widely applied to the fields of proteinlabeling, super-resolution fluorescence imaging and the like.
