Triphenylmethane is a triarylmethane in which the three aryl groups are phenyl. It forms the basic skeleton of several synthetic dyes. It has a role as a xenobiotic and an environmental contaminant. We have explored the application of polysubstituted derivatives of triphenylene as high resolution, high etch durability electron beam resists. Room temperature spin coating was used to produce films of the derivatives on silicon by: Abstract A facile approach to access polysubstituted pyridine derivatives starting from Baylis‐Hillman adducts is disclosed. The reactions proceeded smoothly by sequential AlCl3‐catalyzed condensat Cited by: 2.

The starting 1‐azatriene derivatives were prepared in situ by reaction of 2‐propenylbenzaldehydes with 1,1‐dimethylhydrazine, which exhibited superior performance when compared with other hydrazine derivatives. Temporary hair dyes contain azo, triphenylmethane, anthraquinone, or indamine dyes while semipermanent hair dyes contain nitro-phenylenediamines, nitro-aminophenols, and some azo dyes. Permanent hair dyes differ from semipermanent or temporary dyes in that permanent hair dyes consist of two components that are mixed before use and generate the. Azo dyes have di versity in will be studied in three different groups depending on the chemical structures with an overview on the synthesis of some new dyes, color index numbers (C.I.) and. D.R. Waring, in Comprehensive Heterocyclic Chemistry, Anthraquinone Dyes. Anthraquinone dyes are very important generally in dye chemistry and depending upon the nature of the substitution provide bright red to greenish-blue dyes. There are, however, few heterocyclic analogues of importance in disperse dye chemistry.

K. CARR, in Colorants for Non-Textile Applications, Xanthenes. Xanthene dyes with their narrow absorption curves and tendency to fluoresce can be used to produce very bright ink jet prints, and one particular compound to have found extensive application in this area is CI Acid Red 52 (16).Unfortunately, the light-fastness of this chromophoric system is particularly poor. Among the synthetic dyes, triphenylmethane dyes are widely used in the textile and dyeing industries (Azmi et al. , Thetford Methyl Violet (MV) is a commonly used triphenylmethane dye in. The di erent structural forms of the hydroxy xanthene dyes have di derivatives. Journal of Medicinal Chemistry. The photochemistry and photophysics of triphenylmethane dyes in solid. Amongst functional macromolecules, the combination of polymers and dyes is a research field of great potential with regard to high-performance materials. Accordingly, colored polymers have become increasingly important as materials for miscellaneous technical applications in recent years while also being a major part of everyday life. For instance, dye-containing polymers are nowadays widely.
