Controlling the secondary assembly of porous anionic uranyl-organic polyhedra through organic cationic templates

Herein, we report a new uranyl-organic polyhedron U 4 L 4 (L = BTPCA) assembled from uranyl and a semirigid tritopic ligand. By adjusting the carbon chain length of organic templates, two complexes can be obtained based on the diverse secondary assembly of U 4 L 4 cages. The mechanism of different a...

Summary:Herein, we report a new uranyl-organic polyhedron U 4 L 4 (L = BTPCA) assembled from uranyl and a semirigid tritopic ligand. By adjusting the carbon chain length of organic templates, two complexes can be obtained based on the diverse secondary assembly of U 4 L 4 cages. The mechanism of different arrangements of U 4 L 4 cages induced by organic templates was explored in detail. This work presents a new uranyl-organic polyhedron U 4 L 4 assembled from uranyl and a semirigid ligand. By adjusting the carbon chain length of organic templates, the secondary assembly of U 4 L 4 nanocages is achieved.
