In contrast to conventional stepwise synthesis of molecular Borromean rings, a self‐assembly synthetic method which proceeds without the aid of a template has been developed. In the formation of molecular rectangles, by adjustment of the long‐arm length of the rectangles, a series of size‐dependent Borromean‐link frameworks were constructed. Both the shortest length of two arms and the relative proportion of the length of the long arm to that of the short arm play a key role in the formation of Borromean rings. DFT calculations were used to provide theoretical support for the formation of discrete interlocked frameworks.
