从Yb（OAc）3·4 H2O和Yb（NO3）3·6 H2O与H2 L（H2 L = N，N′-bis（salylidene）-1，2-phenylene-diamine）的反应中，分离得到了独特的四齿Salen型三层夹心式双核镱配合物[Yb 2L 3（CH 3OH）]·0.5H2O（1）和三层夹心式三核镱配合物[Yb 3L 3（CH 3OH）2（NO3）3]·CH 3OH·5 H2O（2）.配合物1与Yb（NO3）3·6 H2O反应生成配合物2。对配合物1和2的近红外（NIR）稀土发光和寿命进行了研究和描述。
Unique quadridentate salen type triple-decker dinuclear sandwich ytterbium complex [Yb2L3(CH3OH)]·0.5H2O (1) and triple-decker trinuclear sandwich ytterbium complex [Yb3L3(CH3OH)2(NO3)3]·CH3OH·5H2O (2) are isolated from the reactions of Yb(OAc)3·4H2O and Yb(NO3)3·6H2O with H2L, respectively (H2L = N,N′-bis(salicylidene)-1,2-(phenylene-diamine)). Complex 2 could be harvested from the addition of complex 1 and Yb(NO3)3·6H2O. Near infrared (NIR) lanthanide luminescence and the lifetime of complexes 1 and 2 are conducted and described.
