in diverse solvents such as water, ethanol, methanol, ethyl acetate and N, N-dimethylformamide. Fluorescence spectra are taken in water and highest fluorescence was exhibited by dyes containing carboxylic groups. The ʎmax and fluorescence of these dyes is greatly affected by polarity of solvents. The structures of newly synthesized rylene-azo hybrid dyes have been confirmed by UV, FTIR and 1HNMR spectroscopy
通过偶氮染料与四氯苝二酐的缩合合成了新型的茚-偶氮杂化染料,具有惊人的热、化学和光化学稳定性。酚类偶氮染料用于对苝 3,4,9,10-二酐体系 1,6,7,12-位上的氯取代基进行亲核取代。这些染料的吸收最大值 (ʎ max ) 已在不同的溶剂中测定,例如水、乙醇、甲醇、乙酸乙酯和 N, N-二甲基甲酰胺。荧光光谱是在水中拍摄的,含有羧基的染料表现出最高的荧光。这些染料的 ʎ max和荧光受溶剂极性的影响很大。新合成的茚-偶氮杂化染料的结构已通过紫外、红外和红外光谱证实1 HNMR光谱。
