UV/Vis absorption, fluorescence and excitation spectra as well as the fluorescence quantum yields of the prepared compounds were measured in 1,4-dioxane, ethyl acetate, dibutyl ether and acetonitrile; nanosecond kinetics of the fluorescence decay was measured in different solvents. The influence of the character of the substituent on triazinyl ring and of the solvent polarity upon the absorption and fluorescence
N-(4,6-二氯-1,3,5-三嗪-2-基)-2-氨基蒽是通过将2,4,6-三氯-1,3,5-三嗪的一个氯原子取代而合成的2-氨基蒽。通过亲核取代N上一个或两个氯原子制备了一系列新的N-三嗪基-2-氨基蒽-(4,6-二氯-1,3,5-三嗪-2-基)-2-氨基蒽,具有供电子的甲氧基或苯氨基基团。在1,4-二恶烷,乙酸乙酯,二丁醚和乙腈中测量了所制备化合物的UV / Vis吸收,荧光和激发光谱以及荧光量子产率。在不同的溶剂中测量了荧光衰减的纳秒动力学。讨论了取代基在三嗪基环上的性质以及溶剂极性对吸收光谱和荧光光谱以及荧光量子产率的影响。
