Collection: Near-Infrared (NIR) Dyes

Near-Infrared (NIR) Dyes — a collection of dyes and metal dithiolate complexes that absorb and emit light in the near-infrared range, including nickel dithiolate complexes, cyanine derivatives such as IR-813 and IR-754, and copper-metalated naphthalocyanine compounds. This category also includes benzoquinone diiminium derivatives that function as NIR absorbers.

NIR dyes are used in photonics and optical materials research as laser heat absorbers, infrared cut-off filters, and optical imaging components thanks to their strong absorption outside the visible light range. Cyanine derivatives such as DiR and IR-813 are used by cell biology researchers as tracer dyes for NIR fluorescence imaging in in vitro models, while nickel dithiolate complexes and naphthalocyanines are more commonly used in optoelectronic applications such as laser absorbers.

Pay attention to the specific absorption and emission peaks of each compound so they match the laser wavelength or detector being used, as well as solvent solubility and the small pack sizes common for these functional dyes. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
