Synthesis and Physical Properties of Cyanine Dyes as Near Infrared(NIR) Absorbing Dye

초록

A new near infrared(NIR) absorbing dyes were synthesized by using bis-aldehyde formyl compounds and heteroaryl derivatives with the reactive methylene group. These dyes provided a range of the NIR wavelength region about 770~810nm values. Also, the physical properties of these dyes were investigated in our research. In generally, these colorants may be used for optical-data storage, bio-probe and NIR cut-off materials.
