Poly[5-methoxy-2-(3-sulfopropoxy)-1,4-phenylenevinylene] potassium salt solution (APPV) is a sulfonated phenylenevinylene (PPV) that acts as a high sensitive water soluble photo-luminescent (PL) polymer. It has an anionic π-conjugation that allows it to have a high fluorescence quantum yield.

APPV can be used as a light emitting polymer that facilitates the enhancement of the fluorescent properties of plasmonic-3D colloidal crystals. It can also be used as a polyelectrolyte which finds potential applications in organic solar cells (OSCs).

Water soluble, light emitting conjugated polymer.
