光致变色材料以其在近代科学技术及日常生活中的广泛应用，一百多年来一直受到科学家的青睐，如对有机光致变色物质螺吡喃、螺噁嗪及俘精酸酐的研究已非常深入。但光致变色稀土配合物的研究却很少，对含不具有光致变色配体的光致变色稀土配合物的研究未见报道。这便是本篇论文的研究背景。 我们合成了三个不具有光致变色性的配体:N,N-二(N-亚甲基琥珀酰亚胺)β-丙氨酸(MSIA)、N,N-二(N-亚甲基琥珀酰亚胺)γ- 丁氨酸(MSIGABA)和 N,N-二(N-亚甲基琥珀酰亚胺)ε- 己氨酸(MSIDAHA)。通过元素分析、红外、核磁及单晶结构测定，对它们进行了表征并确定了它们的分子结构。我们用这三个配体及邻菲罗啉(phen)合成了八个稀土三元配合物体系:Eu3+-MSIA-phen，La3+-MSIA-phen,Dy3+-MSIA-phen，Sm3+-MSIA-phen,Eu3+-MSIGABA-phen，La３+MSIGABA-phen，Eu3+MSIDAHA-phen及La3+-MSIDAHA-phen。对这八个配合物体系均作了可见吸收谱。其褪色曲线证明了其光致变色性质:在光照 下它们能从黄色变成绿色，而避光后，又褪回成黄色。通过实验，我们发现它们的光致变色性质与溶液 pH 值、溶剂、稀土离子及配体有关。pH 值在 5-6.5 范围内，光致变色效果最好。水是目前为止，我们所发现的最好的溶剂。在其他溶剂如甲醇、乙醇、丙酮中，该体系均无光致变色现象。配合物的褪色时间从Eu3+、La3+、Sm3+到Dy3+依次增加。含 MSIA的三元配合物体系的光致变色性最好。含MSIGABA及MSIDAHA的配合物体系次之。 此外，我们还用电喷雾质谱研究了这三个配体及八个配合物体系，并得到一些可供解释配合物体系组成的碎片。

In the last ten decades, photochromic materials have received wide study by scientists because of their comprehensive application in modern scientific technique and everyday life. For example, there have been deep and complete study in organic photochromic compounds such as spiropyrans, spirooxazines and fuligides. However, little attention has been paid to rare earth photochromic complexes, let alone those ones that have non-photochromic ligands. It is really a big blank. This is what makes us exciting to explore this brand new field and is also the background of this dissertation. We synthesized three different non-photochromic ligands:N.N-bis(N-methylenesuccimido) β -alanine (MSIA),N.N-bis(N-methylenesuccimido)y . aminobutyric acid (MSIGABA) and N.N-bis(N-methylenesuccimido)ε -aminohexanoic acid (MSIDAHA).And they were characterized by elemental analysis,IR and １H NMR.Through single crystal X-ray diffraction, their structure can finally been set. Then by use of these ligands and o-phenanthroline (phen), we synthesized the following eight systems of ternary rare earth photochromic complexes:Eu3+＿MSIA-phen,La3+＿MSIA-phen,Dy3+＿MSIA-phen,Sm*-MSIA-phen,Eu3+＿MSIGABA-phen,La3+＿SIGABA-phen,Eu3+＿ＭSIDAHA-phen and La*-MSIDAHA-phen. Visible spectra were applied to study these eight complexes systems and their decay curves proved their photochromism: they can turn from yellow to green when they are under the sunlight or certain intensity of Hg lamp and come back to green when avoided light. In addition, through experiments, we found that their photochromism was relative to four factors: the pH value of the solution,the kind of solvent, the rare earth ions and the ligands. Photochromism of the ternary complex systems is excellent when the pH value of the solution ranges from 5 to 6.5; Water is the best solvent for such systems. Among other solvents such as methanol, ethanol and acetone, the systems have no photochromism The time required for such systems to turn from green back to yellow increases from Eu3+,La3+，Sm3+ to Dy3+.Ternary complexes with ligands of MSIA show better photochromism than that that of those with the ligands of MSIGABA and MSIDAHA. Beside, we studied the three ligands and the eight ternary complexes systems by electrospray ionization (ESI) technique and got their ESI-Mass Spectra. After careful analysis, we acquired some useful fragments.
