Molecular modeling of Congo Red analogues containing terphenyl and quarterphenyl moieties

Autor: Harold S. Freeman, Jason Lye, Russell D. Cox

Publikováno v: Dyes and Pigments. 47:53-64

The molecular structures of Congo Red and its terphenyl and quarterphenyl analogues were optimized by applying AM1 and PM3 semiempirical methods to partially optimized starting structures. It was necessary to carry out repetitive sequences consisting

Molecular Modeling in Dye Chemistry: Studies Involving Two Disperse Dyes

Autor: Harold S. Freeman, Jason Lye, David Hinks

Publikováno v: Textile Research Journal. 69:583-590

The equilibrium geometries of C.I. Disperse Yellow 86 and C.I. Disperse Red 167 are predicted using semi-empirical and mechanical methods. All semi-empirical geometry optimizations involve MNDO, MINDO/3, AM1. and PM3 Hamiltonians implemented in MOPAC

X-ray crystal structure of C.I. Disperse Yellow 86

Autor: Mary E. Mason, Harold S. Freeman, Phirtu Singh, Jason Lye

Publikováno v: Dyes and Pigments. 42:107-111

In conjunction with studies pertaining to the design of lightfast dyes for PET, the X-ray crystal structure of C.I. Disperse Yellow 86 has been solved to R=0.067 using 1999 independent reflections of MoKα radiation, collected by the ω-scan method a

Disperse dyes containing a built-in oxalanilide stabilizer

Autor: Harold S. Freeman, Mary E. Mason, Jason Lye

Publikováno v: Dyes and Pigments. 42:53-63

Monoazo and nitrodiphenylamine disperse dyes containing an oxalanilide photostabilizer have been synthesized and evaluated for lightfastness as potential automotive dyes. The results showed that the lightfastness of CI Disperse Red 167 could be appre
