Two series of eight new rare earth complexes were synthesized by refluxcondensation method in my thesis. Their compositions and structures werecharacterized by Elemental analysis, ICP, UV-VIS, FT-IR, XPS, TG-DTA, XRD,1HNMR,MS and TEM etc. The compositions of the first series of complexes were confirmed tobe: Na[RE(8-hq)2(2-pfica)2](RE=Y3+、La3+、Pr3+、Nd3+、Sm3+、Er3+;2-pfica=picolinicacid;8-hq=8-hydroxyquinoline), The compositions of the second series of complexeswere confirmed to be: RE(S-SBA-15)3(RE=La3+and Y...
