Ionic perylenetetracarboxdiimides: Highly fluorescent and water-soluble dyes for biolabeling

Qu, Jianqiang,Kohl, Christopher,Pottek, Mark,Muellen, Klaus

, p. 1528 - 1531 (2004)

Dying to be seen: A series of water-soluble and highly fluorescent perylenetetracarboxdiimides (PDIs) have been synthesized in high yields by introducing charged groups into the bay region of PDI (see picture; C gray, H white, S yellow, O red). They can be used for staining living cells as they are nontoxic.
