摘要

A series of C_(3i)-symmetric bicapped trigonal antiprismatic Cd_8 cages [2X@Cd_8L_6(H_2O) _6]?n Y?solvents (X=Cl~-, Y=NO_3 ~-, n=2: MOCC-4; X=Br~-, Y=NO_3 ~-, n=2: MOCC-5; X=NO_3 ~-, Y=NO_3 ~-, n=2: MOCC-6; X=NO_3 ~-, Y=BF_4 ~-, n=2: MOCC-7; X=NO_3 ~-, Y=ClO_4 ~-, n=2: MOCC-8; X=CO_3 ~(2-), n=0: MOCC-9), doubly anion templated by different anions, were solvothermally synthesized by means of a flexible ligand. Interestingly, the CO_3 ~(2-) template for MOCC-9 was generated in situ by two-step decomposition of DMF solvent. For other MOCCs, spherical or trigonal monovalent anions could also play the role of template in their formation. The template abilities of these anions in the formation of the cages were experimentally studied and are discussed for the first time. Anion exchange of MOCC-8 was carried out and showed anion-size selectivity. All of the cage-like compounds emit strong luminescence at room temperature. Metal-organic coordination cages: A series of C_(3i)-symmetric bicapped trigonal-antiprismatic Cd_8 cages, doubly anion templated by different anions, have been solvothermally synthesized by using a flexible ligand. The templating abilities of these anions in the formation of the cages (see figure) have been experimentally studied.
