Self-sorting of porous Cu4L2L′2 metal–organic cages composed of isomerisable ligands†
Abstract
We report the self-sorting of a dynamic combinatorial library (DCL) of metal–organic cages composed of a rotationally isomerisable ligand. Convergence of the DCL occurs upon crystallisation and leads to low-symmetry Cu4L2L′2 cages that display differing porosities based on their overall shape and ligand configuration.
