| 摘 要： | 通过将相应的席夫碱穴醚还原的方法合成了三个具有不同取代基（R=溴，4；苯基，5；甲基，6）的新的酚羟基桥的八胺穴醚，并对其进行了表征。将这些新穴醚与镧系元素的高氯酸盐反应制备了它们的镧系元素配合物(7～12)。核磁、质谱、红外、紫外和元素分析等表征结果表明这些镧系元素配合物为单核配合物并可能具有N3O3N3型的对称配位结构。讨论了铕(Ⅲ)配合物8在乙腈溶液中的荧光性质。 |

| Abstract: | Three new phenolate-bridged octaamino cryptands (R= Bromo, 4; Phenyl, 5; Methyl, 6) were synthesized in high yield by reduction of the corresponding Robson-type Schiff-base cryptands derived from a 2 3 condensation of tris(2-aminoethyl)-amine and 2,6-diformyl-4-R-Phenol. The lanthanide cryptates (7~12) were obtained by treating the cryptands with lanthanide perchlorates. All compounds were carefully characterized by NMR, mass spectra, IR, UV-Vis and elemental analyses. A new type of N3O3N3 symmetric coordination geometry around the mononuclear lanthanide(III) ion encapsulated within the cryptand cavity was proposed. The luminescence property of europium(III) cryptate 8 in acetonitrile solution was also discussed. |
