Bis-Indole Cyanine Dye (XVI) - Molecular Structure and Applications #1760960 (License: Personal Use)

This image displays the 2D skeletal structure of compound (XVI), a bis-indole cyanine dye characterized by two sulfonated indole moieties connected via a polyene bridge and a terminal norbornene-derived amide group. The molecule includes a quaternary nitrogen on one indole ring, enhancing its cationic nature and water solubility, while the SO₃⁻ groups improve biocompatibility. Designed for bioconjugation and fluorescence applications, it serves as a photosensitizer or probe in cellular imaging and targeted photodynamic therapy.

Used in scientific publications, chemistry databases, and product pages for fluorescent dyes; targets researchers in medicinal chemistry, bioimaging, and materials science seeking structural insights for synthesis or application planning.
