Construction of a nano-rectangular Zn-Nd complex with near-infrared luminescent response towards metal ions

One 6-metal Zn-Nd complex [Zn2Nd4L2(OAc)(10)(OH)(2)(CH3OH)2] (1) with Schiff base ligand bis(3-methoxysalicylidene)ethylene-1,2-phenylenediamine (H2L) was constructed, and it has nanoscale rectangular structure (8 x 11 x 28 angstrom). Excited by ligand-centered absorption bands, 1 shows NIR emission of Nd3+ ion. Interestingly, 1 exhibits lanthanide luminescent response towards metal ions, especially to alkali metal ions (Li+, Na+ and K+) at ppm level.
