| Abstract: | Six kinds of rare earth metal complexes were synthesized using REC13 and 2-hydroxy-4-methoxy- benzophenone as raw materials and ethanol as solvent. The composition and structure of the complexes were characterized by elemental analysis,IR,UV and TG/DTA. The experimental results showed the composition of complex was RE（C14 H11O3）3 ,and the complex ratio of rare earth metal ion to 2-hydroxy-4-methoxybenzophe- none was 1 ： 3. Rare earth metal ions coordinated with oxygen atoms of C= O and next to --OH group. The complexes still had the ability to absorb ultraviolet light,and their thermal stability were superior to that of lig- and 2-hydroxy-4-methoxybenzophenone. |
