【摘要】 以4,4′,4″ 三氨基三苯胺为母体,以含有4种不同取代基的萘酚AS为偶合组分合成了一系列三芳胺三偶氮类有机光导颜料.用元素分析、红外光谱、紫外光谱、质谱和X射线衍射光谱对结构进行了表征.研究结果表明,含硫杂环三偶氮类有机光导颜料在520—730nm之间都有较强吸收.更多还原

【Abstract】 A series of trisazo pigments were synthesized by coupling 4,4′,4″triaminotriphenylamine with various 2hydroxy3naphthanilides containing different substitutesTheir structures were characterized by elemental analysis,IRspectra,UVVis spectra,Mass spectra and Xray diffraction patternsThe UVVis spectra show that the absorption spectra of these trisazo pigments are not only in the visible region but also in the nearinfrared region更多还原
