General description
Coumarin 343 is a small hydrophilic dye. It is unable to penetrate the cell membrane by itself. Coumarin 343 is also known as coumarin 519. Depending on the pH of the medium, coumarin 343 exists in neutral and anionic forms.
Application
Coumarin 343 has been used in many different applications that include solution dynamic probes, laser dyes, and organic sensitizers in dye-sensitized solar cells.
It is suitable to study photo-induced charge injection into other metal oxides such as TiO2, ZrO2, and ZnO.
