研究了蒽醌冠醚及其铕离子络合物的光物理性质 .研究结果表明 ,选择性激发铕离子络合物中的蒽醌冠醚能发生分子内能量转移 ,观察到铕离子的发光 .荧光衰减测试表明由于冠醚的包络作用使得铕离子络合物的荧光寿命较未络合铕离子的寿命有所延长 .向蒽醌冠醚铕离子络合物的甲基四氢呋喃溶液中加入水后 ,其荧光强度明显减弱 ,这说明了蒽醌冠醚对铕离子的络合作用不完全 ,未能有效地阻挡水和溶剂对铕离子的影响 . The photophysical properties of anthraquinone crown ether and its europium ion complex were studied.The results show that intramolecular energy transfer can be induced by selective excitation of anthraquinone crown ether in europium ion complex and the luminescence of europium ion is observed. Fluorescence decay test showed that the fluorescence lifetime of the europium ion complex was longer than that of the uncomplexed europium ion because of the enveloping effect of crown ether.When the solution of anthraquinone crown ether europium complex in methyltetrahydrofuran was added water After which the fluorescence intensity was obviously weakened, which indicated that the complexation of anthraquinone crown ether with europium ion was incomplete and the effect of water and solvent on europium ion was not blocked effectively.
