School of Chemistry and Chemical Technology University of Bradford Bradford West Yorkshire BD7 1DP The synthesis of a series of 2′, 4′, 6′‐trisubstituted derivatives of 4–N–β–hydroxyethyl–4– N–β–cyanoeth ylaminoazobenzene is reported, and the effect of the nature of the substituents on the colour, dyeing and fastness properties of these dyes is described. The dyes coloured synthetic–polymer fibres well, with the exception of those containing a methylsulphonyl group, which gave weaker dyeings on polyester. Dyes substituted by 2′‐nitro groups tended to have poor light fastness, and reasons for the variations in the light fastness of monoazo dyes of this type are discussed.

“…In addition, fluorine-containing dyes show excellent color fastness [24,25]. The electron-withdrawing effect of fluorine and, in particular, the trifluoromethyl group can be used to tune the electronic levels and thus the color.…”

“…16 Moreover, uorinated azo compounds exhibit greater stability to light than their non-uorinated homologs. 17 On the other hand, the rapid development in the area of optical storage devices leads to signicant interest in liquid crystalline materials from uorobenzene derivatives. [18][19][20] It has been reported recently by M. R. Lutfor et al, on pentauorosubstituted azobenzene moiety and their liquid crystalline behaviour along with photoswitching property.…”
