Synthetic Design of Infrared Absorbing Dyesnterest recently in the development of functional materials for diode-laser technologies, comprise a very new category of dyes, and their synthetic design should be based on the new ideas and methodology discussed in Chapter 1.

Cyanine Dyesteroaromatic residue, and λ. is affected strongly by the electronic characteristics of R. The length of an ethylene unit in the conjugating bridge also strongly affects λ., and near-infrared absorption generally can be attained for . > 3.

Quinone Dyesmistry of quinone dyes was reviewed thoroughly by Venkataraman. in 1971. Gordon and Gregory. also reviewed advances in anthraquinone dye chemistry in 1983, but they did not describe the infrared absorbing quinone dyes.

Other Chromophoresomplex dyes, as described in the previous chapters. Azo dyes are the most popular chromophore but generally absorb in the visible region. The well-known deep-colored azo disperse dyes have the general formula . and absorb below 650 nm.
