In the first part, a thermordynamically stable monomeric cage was obtained and the transformation from the monomeric cage to dimeric cage and even to a triple catenane was realized by varying the amount of halide anions. In the second part, a peanut-shape cage and its interpenetration cage were obtained by elongating the backbones. In the last part, two multi-component heteroleptic coordination cages were achieved from two different ligands via side-chain directed complimentary coordination strategy.
