SYNTHESIS AND ELECTRONIC ABSORPTION SPECTRA OF SOME METHOXY HALF-ANALOGUE OF MICHLER'S HYDROL BLUE
Abstract
The present work comprises the synthesis of one series of diarylmethane dyes
containing one or more terminal methoxy substituents together with a variable
tertiary amino group. The electronic absorption spectra of the dyes have been
determined. As the conjugation of the terminal nitrogen atom improves in the
sequence NMez > Kairoline > Julolidine, a progressive hypsochromic shift
is observed
