General description

Difluoro{3-ethyl-5-[1-(4-ethyl-3,5-dimethyl-2H-pyrrol-2-ylidene-N)ethyl]-2,4-dimethyl-1H-pyrrolato-N}boron is a pyrromethene dye that is majorly used in liquid and solid state lasers. Its properties include low intersystem crossing and low triplet-triplet absorption which results in a high fluorescent quantum yields.

Application

BODIPY laser dyes are used to generate fluorescent conjugates of proteins; nucleotides; oligonucleotides and dextrans; and to prepare fluorescent enzyme substrates; fatty acids; phospholipids; lipopolysaccharides; receptor ligands and polystyrene microspheres.

Used for solid-state dye laser devices.
Difluoro{3-ethyl-5-[1-(4-ethyl-3,5-dimethyl-2H-pyrrol-2-ylidene-N)ethyl]-2,4-dimethyl-1H-pyrrolato-N}boron can used in the fabrication of lasers for a variety of applications such as optoelectronics, and high intensity data storage.
