Construction of a Nano‐rectangular Zn(II)‐Yb(III) Complex with Near‐Infrared Luminescent Response towards Metal Ions

Abstract

of main observation and conclusion One six-metal Zn(II)-Yb(III) complex [Zn 2 Yb 4 L 2 (OAc) 10 (OH) 2 (CH 3 OH) 2 ] (1) was constructed from Schiff base ligand bis(3-methoxysalicylidene)ethylene-1,2-phenylenediamine (H 2 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.

Construction of a Cd8Tb4 nanoring for luminescence response to 2,6-dipicolinic acid as an anthrax biomarker

“…The Tb-O, Cd-O and Cd-N bond lengths are 2.31(2)-2.86(2) Å, 2.23(2)-2.54(2) Å and 2.22(2)-2.39(2) Å, respectively, which are comparable to those found in the Schiff base Cd(II)-Ln(III) complexes reported before. [21][22][23] The distribution of Cd(II) and Tb(III) in 1 could be observed in the energy dispersive analysis of X-ray (EDAX) images (Fig. 2a).…”

Photoluminescence Anisotropy in Eutectic Crystals of Polynuclear Lanthanide Complexes and Silver Clusters

“…Lanthanide complex light‐emitting materials usually have the advantages of high luminous intensity, good monochromaticity and adjustable color [14] . In the last decade, there has been considerable activity in the field of luminescence [15] . Several other studies on the influence of the luminescence as a function of the orientation of the lanthanide complexes have been reported proved very promising to realize polarized light [16] .…”

“…[14] In the last decade, there has been considerable activity in the field of luminescence. [15] Several other studies on the influence of the luminescence as a function of the orientation of the lanthanide complexes have been reported proved very promising to realize polarized light. [16] However, up to now, the structurally accurate solid crystalline materials with lanthanide complexes as building elements for polarized light emitting in the visible light range have hardly been realized.…”
