  • Cyanine - Wikipedia
    Although the name derives etymologically from terms for shades of blue, the cyanine family covers the electromagnetic spectrum from near IR to UV Chemically, cyanines are a conjugated system between two nitrogen atoms; in each resonance structure, exactly one nitrogen atom is oxidized to an iminium
  • Fundamentals in the chemistry of cyanine dyes: A review
    The developments of cyanine dyes synthesis and their applications in photographic and non-photographic multidisciplinary areas are growing continuously, significantly and rapidly Certainly, this will make the present and the future of cyanine dyes chemistry effective, fruitful and very bright
  • Cyanine Dyes: Definition, Structure, Types and Uses
    Cyanine (Cy), also known as tetramethylindole (di)-carbon cyanine, is a synthetic dye belonging to the polymethine family The cyanine family covers a wide spectral range from near-infrared to ultraviolet
  • Cyanine dyes - Lumiprobe
    Cyanine dyes are molecules containing polymethine bridge between two nitrogen atoms with a delocalized charge: Due to their structure, cyanines have outstandingly high extinction coefficients often exceeding 100,000 Lmol-1 cm-1 Different substituents allow to control properties of the chromophore, such as absorbance wavelength, photostability
  • 4. 2: Cyanine Dyes - Chemistry LibreTexts
    Cyanine dye molecules, which have the general structure shown in Figure \(\PageIndex{1}\), are planar cations The number of carbon atoms in the chain can vary, as can the nature of the end groups containing the nitrogen atoms
  • Mechanism of Cyanine5 to Cyanine3 Photoconversion and Its Application . . .
    The polymethine chain, the signature chromophore of cyanine dyes, offers a chemical basis for a range of photophysical properties such as cis–trans photoisomerization, photoswitching, and oxidative photolysis
  • Cyanine dye | Synthesis, Fluorescence, Photostability | Britannica
    cyanine dye, any member of a class of highly coloured organic compounds used for increasing the range of wavelengths of light to which photographic emulsions are sensitive A few members of the class are used in textile dyeing, but most are too easily destroyed by acids or by light to be satisfactory for this purpose
  • Cy2 (Cyanine2) | Fluorescent Dye - MedChemExpress
    The structures and optical properties of representative cyanine dyes used for in vivo imaging are presented Cyanines are characterized by long wavelength, tunable absorption and emission, very high extinction coefficient (up to 300,000 M 1 cm 1), good water solubility, and relatively straightforward synthesis
  • An Overview of Cyanine Dyes: Types, Wavelengths, and Applications . . .
    Cyanine dyes are versatile synthetic compounds known for their vivid colors and broad utility across scientific, medical, and industrial fields Characterized by two nitrogen-containing heterocycles connected by a polymethine bridge, cyanine dyes offer tunable absorption and emission wavelengths, high photostability, and customizable solubility
