Controlling the secondary assembly of porous anionic uranyl–organic polyhedra through organic cationic templates†
Abstract
Herein, we report a new uranyl–organic polyhedron U4L4 (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 U4L4 cages. The mechanism of different arrangements of U4L4 cages induced by organic templates was explored in detail.
