本文选用28种不同结构的偶氮化合物进行光褪色研究。实验表明,化合物在广泛波谱范围内光照条件下光褪色反应符合光化反应一级动力学规律。本文定义并测定了化合物在实验条件下的固有褪色率K,对化合物的有关分子性质进行了HMO计算,并通过多元线性回归处理,分别获得两个描述固有褪色率的经验公式; ln K_1=-77.12 HSS_a~E+163.12 HSS_c~E+228.85 AP_(nn)-200.75 ln K_2=29.77 ASS_a~E-37.56方差分析表明,回归结果可信程度较高。本文同时还对化合物在实验条件下光褪色的可能机理进行了探讨。
In this paper, 28 different structures of azo compounds for light fading research. Experiments show that the compounds in a wide range of spectral light photochromic reaction conditions consistent with the photochemical reaction first-order kinetics. In this paper, we defined and determined the inherent decolorization rate K of the compounds under the experimental conditions, calculated HMO of the related molecular properties of the compounds, and obtained two empirical formulas describing the inherent decolorization rate by multiple linear regression. Ln K_1 = - 77.12 HSS_a ~ E + 163.12 HSS_c ~ E + 228.85 AP_ (nn) -200.75 ln K_2 = 29.77 ASS_a ~ E-37.56 ANOVA showed that the regression results were more credible. In this paper, the possible mechanism of light fading of compounds under experimental conditions was also discussed.
