Single code self-assembly

Self-assembled systems can be classified according to the diversity of interactions that they contain. Single-interaction self-assembly (sometimes referred to as single code self-assembly) refers to systems in which only one specific interaction is present (Figure 3.3(a)). For example, the palladium/bipyridyl square (3.1) in... 

Lehn and coworkers developed a similar approach, which they term double code or double subroutine self-assembly. In this technique different metal ions in a mixture are induced to selectively interact with different binding sites on a single, hybrid ligand, giving assemblies displaying novel structures. An example of such a process is shown in Fig. 2. ...
