K + and K + , respectively. The largest change in fluorescence behavior was observed for the copolymer bearing aza-18-crown-6 in the presence of K + . The magnitude of the increase in the fluorescence intensity was related to the content of the crown ether moiety. The time-dependent changes in the fluorescence spectra using photo-irradiation were also investigated.
摘要用N -2-乙基氮杂正丁醚或9-羟甲基蒽的甲基丙烯酸酯合成了具有氮杂冠醚和蒽部分的共聚物。在THF:H 2 O = 10:1溶液中测量了它们在碱金属离子存在下的荧光行为。观察到分别带有Na +,K +和K +的带有aza-12-crown-4、15-crown-5和18-crown-6的共聚物的最大荧光强度。在K +存在下,对于带有aza-18-crown-6的共聚物,观察到最大的荧光行为变化。荧光强度增加的幅度与冠醚部分的含量有关。还研究了光辐照下荧光光谱随时间的变化。
