Lightfastness modelling of azo dyes bearing heteroaromatic substituents

Lightfastness for a number of azo dyes bearing heteroaromatic substituents was modelled by the partial least squares method (PLS) in terms of structural descriptors, involving the principal properties of usual substituents, and the chemical shifts of the heteroaromatic moieties. The model permits th...

Zusammenfassung:Lightfastness for a number of azo dyes bearing heteroaromatic substituents was modelled by the partial least squares method (PLS) in terms of structural descriptors, involving the principal properties of usual substituents, and the chemical shifts of the heteroaromatic moieties. The model permits the prediction of possible structures, with higher values of the technological property, worthy of synthesis.
