标题：anion dependent self-assembly of drum-like 30- and 32-metal cdln nanoclusters: visible and nir luminescent sensing of metal
cations

abstact：two types of drum-like 30- and 32-metal cd-ln nanoclusters [ln8cd24l12(oac)48] (ln = sm (1), yb (2), er (3)) and [er8cd22l12(oac)38(oh)6] (4) were constructed using a designed schiff base ligand built around a flexible (ch2)7 chain. hydroxide (oh-) anions are found in the structure of 4, indicating that the basic environment favors the formation of 30- metal cluster. the chromogenic cd/l components in these clusters can act as efficient sensitizers for lanthanide luminescence. with the ln(iii) centers enclosed within the drum-like structures, 1-4 display the typical emission spectra of lanthanide ions. for the cd-er clusters, 3 exhibits better nir luminescence properties than 4. the long-chain schiff base ligands show “linear” configurations in these clusters, resulting in the large sizes of 1-4. the drum-like structures of 1-4 have inner cavities with the internal sizes approximately 6 × 11 × 11 å, and some solvent molecules such as h2o, meoh and etoh are enclosed in the drums. interestingly, the cd-sm cluster 1 shows visible and nir luminescent sensing of metal cations and exhibits high selectivity to zn2 and fe3 ions
