摘要

One six-metal Zn(ll)-Yb(lll)complex[Zn2Yb4L2(OAc)10(OH)2(CH3OH)2](1)was constructed from Schiff base ligand bis(3-methoxysalicylidene)ethylene-1,2-phenylenediamine(H2L).1 shows a nanoscale rectangular structure with dimensions of approximately 0.8 nm × 1.1 nm ×2.8 nm.Excited by ligand-centered absorption bands,1 shows typicalnear-infrared emission of Yb3+ ion.Interestingly,1 exhibits lanthanide luminescent response towards metal ions,especially to Cd2+ at ppm level.
