We provide a broad variety of dyes in categories such laser, infrared, chemiluminescent, phthalocyanine/porphyrin, photochromic, and thermochromic in our photonic and optical materials. With our wide range of products, we shed light on your study into light management and display technologies.
Coumarin Dyes
Coumarins are aromatic lactone compounds. The electron-giving group at position 7 of coumarin compounds exhibits high light absorption and luminescence. The wavelength of light absorption and luminescence is substantially controlled by the introduction of a group at the 3 or 4 position. Laser dyes that emit blue-green light can be created using coumarin dyes.
NLO Materials
NLO materials effectively exhibit nonlinear optical phenomena, i.e. light wavelength conversion, light amplification, and refractive index conversion depending on light intensity.
DCM Dyes
DCM dyes consist of pyrimidine malononitrile as an electron acceptor and 4-aminostyryl as an electron donor. This dye is an effective, long-lasting low band gap substance.
Dipyrrole Methylene Dyes
Dipyrrole methylene dyes are used in electronic materials, laser dyes, and fluorescent labeling reagents. The optical characteristics of boron dipyrrole methylene can be controlled more easily chemically than with other fluorescent dyes.
Anthocyanine Dyes
The core polymethynyl structure of anthocyanine dyes exhibits charge transfer that results in light absorption. Anthocyanine dyes can be applied to silver photography and to optical recording medium with laser sensitivity. In biochemical research, water-soluble anthocyanine dyes are employed as fluorescent probes.
Thermosensitive Dyes
Phthalate compounds are colorless dyes that develop color through a ring-opening reaction when interacting with acids.
Near Infrared (NIR) Dyes
NIR dyes show light absorption in the near-infrared region from 700-2000 nm. Their strong absorption usually results from the charge transfer of organic dyes or metal complexes.
Quinacridone Dyes
Quinacridone dyes were originally used as red pigments with clear color and durability. In the field of organic electronics research, quinacridone dyes are used in solar cells and organic light-emitting diodes.
