title: Water-soluble pyrrolopyrrole cyanine (PPCy) NIR fluorophores.
abstract: Water-soluble derivatives of pyrrolopyrrole cyanines (PPCys) have been synthesized by a post-synthetic modification route. In highly polar media, these dyes are excellent NIR fluorophores. Labeling experiments show how these novel dyes are internalized into mammalian cells.
