摘要
Abstract
Three novel azocalix [4] arene compounds were synthesized through diazo-coupling reaction using calix [4] arene, benzocaine, tricaine and procaine hydrochloride as raw materials, and the yield of com⁃pounds 6a, 6b and 6c was up to 83%, 81% and 83%, respectively. The compound structure was character⁃ized by IR, 1H NMR and elemental analysis. The spectra properties of azocalix [4] arene in different pH of solu⁃tion were investigated by UV-Vis. The dyeing properties were studied by the dyeing curve, color depth and fastness test. The results indicated that the increase of pH led to azo-quinoid tautomerizm phenomena of azo⁃calix [4] arene compounds 6a, 6b and 6c, and the maximum absorption peak occurred red-shift. The novel azo⁃calix [4] arene compounds had an outstanding dyeing ability under basic condition than acid condition, and the dyeing percentage of compound 6a was as high as 78%, the K/S value was 2.798, the soaping fastness and dry and wet rubbing fastnesses were al level 4, indicating the compound 6a was a good disperse dye.关键词
