In the case of [Rh4Cu4] cages, up to six-fold-stacked host-guest structures were formed by varying the cavity's dimensions. Moreover, the series of capsules were demonstrated to self-fine-tune to form multi-heteroguest arrays via favourable donor-acceptor interactions and Ag-π interactions, as evidenced from single-crystal X-ray analysis.展开更多
