本文报告了三个含酚羟基取代的苯并噁唑半菁染料、三个不对称菁染料以及一个中间体,共七个新化合物。用元素分析、IR、~1H NMR等证明了它们的结构,测定了其中六个染料的可见光吸收光谱。 In this paper, we report seven new compounds, phenolic hydroxyl-substituted benzoxazole semicarbocyanine, three asymmetric cyanine dyes and one intermediate. Their structures were confirmed by elemental analysis, IR, 1H NMR and so on. The absorption spectra of six dyes were measured.
