Abstract

Summary of main observation and conclusion: One six‐metal Zn(II)‐Yb(III) complex [Zn2 Yb4 L2 (OAc)10 (OH)2 (CH3 OH)2 ] (1 ) was constructed from Schiff base ligand bis(3‐methoxysalicylidene)ethylene‐1, 2‐phenylenediamine (H2 L). 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 typical near‐infrared emission of Yb 3+ ion. Interestingly, 1 exhibits lanthanide luminescent response towards metal ions, especially to Cd 2+ at ppm level.
