Water-soluble small-molecule probes for RNA based on a two-photon fluorescence “off–on” process: systematic analysis in live cell imaging and understanding of structure–activity relationships
The remarkable two-photon fluorescence responses in vitro and in vivo of L1–5 for RNA revealed the synergistic effect of the amino group and the pyridinium cation.
