| چکیده | ||
| 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 | ||
