摘　　要：合成了Ｎ，Ｎ－二（Ｎ－亚甲基琥珀酰亚胺）甘氨酸，并以元素分析、ＩＲ、１ＨＮＭＲ和质谱进行表征．实验中发现铕（Ⅲ）与Ｎ，Ｎ－二（Ｎ－亚甲基琥珀酰亚胺）甘氨酸和１，１０－二氮杂菲形成的配合物具有光致变色的性质．在铕变色物种里，铕离子与Ｎ，Ｎ－二（Ｎ－亚甲基琥珀酰亚胺）甘氨酸中的羧基，１，１０－二氮杂菲中的氮原子相结合。In the present paper, N,Nbis(Nmethylenesuccinimido) glycine(MSIG) was synthesized and characterized by elemental analysis, IR, 1H NMR and MS. It is demonstrated by experiment that the europium complex of MSIG with 1,10phenanthroline has reversible photochromism which occurs rarely in lanthanide complexes. Photochromic behavior of the europium complex was investigated in H2O and H2OC2H5OH solvents. The irradiation of the europium complex solution led to a new absorption band with the maximum wavelength at 616 nm while the color of the solution turned from yellow to green, and when the photolysate was kept in dark, the absorption spectrum turned to its initial figure. The results show that the spectral signal at 616 nm appeared on irradiation and in general disappeared within 1 h at ambient temperature. The yellow color of the europium complex solution turns green rapidly when irradiated as pH of the solution increases in a range of 46. On heating the color changes from green to yellow readily. The ab mismsorption spectra, the fluorescence spectra and the conductance measurement show that the europium ion is bonded to the carboxyl group of MSIG and the nitrogen atoms from 1,10phenanthroline, and probably to water and hydroxyl group in the colored europium species.
