标题：self-assembly of luminescent 12-metal zn–ln planar nanoclusters with sensing properties towards nitro explosives

abstact：two types of zn–ln nanoclusters [nd2zn2l2(l0)2(oac)2(no3)2(h2o)2] (1) and [ln6zn6l2(l00)2o2(oac)18] (ln = nd (2) and sm (3)) were prepared using one long schiff base ligand (h2l) with a naphthyl backbone and two short polydentate ligands (h2l0 and h2l00). 1 and 2–3 show linear and planar structures with sizes of approximately 10  10  30 å and 10  15  22 å, respectively. the chromogenic zn/ligand components can act as efficient sensitizers for lanthanide luminescence, and thus 1–3 show visible and nir emissions. in these clusters, the schiff base ligands display a ‘‘u-shaped’’ configuration, which is suitable to form p interactions and hydrogen bonds with nitro aromatic compounds. interestingly, zn–sm cluster 3 shows visible and nir luminescence sensing of nitro explosives and exhibits high sensitivity to 1,4-dnb and tnt at the ppb level
