摘要: 蒽醌类化合物是一类古老的染料,对光和热非常稳定.某些蒽醌化合物还具有稳定的非晶态和晶态结构,在一定条件下可以进行相互转换,这种材料对强光具有非线性,有潜在的应用背景[1].为此我们设计合成了两种新的蒽醌类化合物,测试了它们在溶液中的吸收光谱,研究了溶液酸碱性对吸收光谱的影响.

Abstract: The absorption spectra of three 2,6-substituted-1,5-dihydroxy-4,8-diamino-9,10-anthraquinone dyes in water-organic mixed solvent were measured at different acidities. The spectral changes were explained. The pKa values corresponding to the different ionisation step were determined. The model molecular structure of the title compounds were calculated by AM1 method. The results are consistent with the experimental phenomenon.

Key words: anthraquinones, absorption spectra, AMI quantum calculation
