| 摘 要： | 研究了9只香豆素类荧光染料(Ⅰ-Ⅶ)的光谱性能和应用性能。香豆素类荧光染料在5’-位有取代基可使最大可见吸收波长和荧光发射波长产生红移;当共轭双键长度增加,可使染料颜色变深(V:544,VI:552)。这9只染料用于涤纶染色有很好的应用性能,差别不大;嗯唑环结构(Ⅰ、Ⅱ、Ⅲ)和喹唑酮结构(Ⅵ)的染料耐光牢度明显好于噻唑环结构(Ⅴ)和咪唑环结构(Ⅶ)的染料。

| Abstract: | The fluorescence properties and application properties of nine coumarin-based fluorescent dyes were studied. The benezoxazolocoumarin dyes substituted with methyl or chlorine on 5'-position showed bathochromic shift of the maximum absorption and fluorescence emission. The benezothiazolocoumarin dyes substituted with chlorine on 5'-position also showed bathochromic shift of the maximum absorption and fluorescence emission. If the conjugate system were extended, the shade of the dyes changed dark. The nine dyes had similar and very good application properties on polyester fibers. The dyes containing benezoxazole ring had better light-fastness than the dyes containing benezothiazole ring and benzimidazole ring. |
